    I\'m thinking Doubler for my 1972 K5, anyone do this yet>>>>>>

    Both my drivelines are toast from the Rubicon /forums/images/icons/mad.gif
    My rig is probly too fast for the Rubicon, even in Granny Low on my SM465 /forums/images/icons/shocked.gif
    SO The old brain starts a tickin....Doubler...Doubler....Doubler???? Need new drivelines anyway!!

    I did a quick look thru and decided to POST up my question.

    I have Sm465 4speed with Np205, I have the dual crossmember holding them up.

    Were is this technoligy now? I know there has been many 'versions' of the 'doubler', so wich one is best for me?
    Can I leave my SM465 installed and just pull the 205 and do whaever the job requires from there?
    And of coarse COST$$$$$$
    So if you had a 350/SM465/NP205 sittin under your rig with no drivelines what kind of doubler would you use/get???

    You = whoever has an opinion... /forums/images/icons/grin.gif /forums/images/icons/grin.gif Stephen??

    I have the doubler.... /forums/images/icons/laugh.gif

    Mine originally had a 350/203.

    I got a sm465/203 and I already had teh th400 version 205.

    So I simply bought the doubler, and doubled up the 203/205.

    I didn't get to use it on the Rubicon, because you WERE IN THE WAY!!! j/k.... as you all know, I turned tail and ran.

    Since you need driveshafts anyway, now is the time to get the doubler in, then measure driveshafts.

    Have fun!
    Good luck.

    i have been wanting to do the same thing....the hardest part is finding a 203 that will mount up to the 465...it took me a good 3 months to find it...the adapter cost me out the ass...the 203 wasent that bad...i just need to come up with the funds to get the actual kit from ORD and i am ready to go....even if you did replace all your drivelines now and waited on the doubler till you can find the 203 parts you can always shorten or lengthin the shafts ass needed relativly cheep..well that is compaired to buying a new shaft all together..but the first step is really trying to find the adapter...that will give you the biggest head ache....i would be willing to part with mine....but......it will cost ya hahaha /forums/images/icons/grin.gif /forums/images/icons/grin.gif j/k...not really lookin to get rid of it...dont feel like trying to find another one /forums/images/icons/grin.gif

    Adapter? What adapter?
    I was under the impresion that ORD supplys all the parts needed to do the swap (except the crossmember)???
    Hmmm, I think I better read more on ORD's site.....

    Stolen off the ORD Website:

    GM SM465 4 speed Manual Transmission:
    If you have an SM465 transmission there are 2 ways to mate it to the NP203.

    1: Use a factory configuration. GM mated the NP203 to the SM465 in 1973-1975 using the 10 spline output in the 465, a 10 spline female input in the NP203 and a 4.25" adapter housing between the two. This configuration was used in a wide range of GM trucks but is somewhat rare. Problems are the 10 spline connection tends to wear in the long term and it's difficult to find. Positives would be the short length and the ability to use the common 10 spline output in the transmission.

    2: Use a SM465 that was originally mated to an NP208 transfer case. This 465 will have a 32 spline output shaft with a 8 3/8" adapter housing. You'll use a NP203 gearbox with a 32 spline input gear and the face of the 203 drilled and tapped with the GM round bolt pattern to match up to the factory 208 adapter housing. This works very well if you have the available length in the vehicle since the parts are commonly available and the 32 spline connection is very strong and durable.

    Actually money is GREAT!.....unfortunately, someone else must have all of mine, because I'm always BROKE! /forums/images/icons/grin.gif

    I dunno Burt....using broken driveshafts as an excuse to get a doubler is REALLY stretching things... I know it will be cheaper to buy the driveshafts at the "correct" length to start with....but having existing shafts shortened and re-balanced is not THAT expensive to have done....at least not expensive enough to spend a couple thou' on the doubler setup.

    I think you need to stay "focused" grasshopper! /forums/images/icons/tongue.gif Get the driveshafts you NEED now....then plan and research the "Ultra Cool Doubler" at a more relaxed pace....there's nothing worse than feeling the pressure to buy an expensive upgrade when you don't fully understand all the details and options.

    Besides....I know that when Burt's truck is sad (broken), Burt is sad. You need to get the truck running soon... Doublers make a great Christmas gift, or Tax-Return purchase ifyougetmydrift! /forums/images/icons/cool.gif

    Re: I\'m thinking Doubler for my 1972 K5, anyone do this yet>>>>>>

    Not quite.

    If you want a sm465/203/doubler/205 you will need

    1) You want to find a SM465/203 adapter ($50-$150)

    2) You need a range box from a 203 that will mate to your sm465. This will most likely be a 10 spline 203 range box (and or complete 203). This will run $50-$150

    3) You will need to get your current 205 MACHINED (see subsections A - C) and retrofitted OR find a 205 that was behind a th400 from 1980-1985.

    A) machine your 205 for the larger bearing (I think this runs about $100)

    B) You will need the larger bearing not sure how much this is.

    C) You will need the 205 input gear (the kind that the original 205 have from behinda th400 (ORD sells this for ~$160)

    Now you need the DOUBLER ($970)

    Finally, you need to get your driveshafts shortened/lengthened. ($50-$75 for each shaft - provided your joints are good.) I would anticipate your front shaft joints are bad = ~$200 - $250

    WWWWWEEEEEEEEEE

    Oh yeah, my front shaft joints are bad... AND DAMN I missed the highangledriveline.com giveway this month!

    Have fun!

    I have pics of me installing my setup.. I need to pull them out of my camcorder, and post them... someday. /forums/images/icons/laugh.gif

    Re: I\'m thinking Doubler for my 1972 K5, anyone do this yet>>>>>>

    I think butch's other adapter came here and left already. Ask him what transfer case came in his K5......
    You need:
    -465/203 housing: used market probably $150
    -203 with 10 spline input (either original OEM or another 203 with a new input) $? New input from us is about $160
    -Doubler kit: $740 and you choose either stock rotation or twist the 205 up about 2". Most everyone gets it rotated up.
    -Shifters: $170

    NP 205 with 32 spline input: either convert yours or buy another
    -Conversion cost:
    ---$200 for input, bearing, and seal and gasket kit
    ---Approx. $50-$70 for the machine work on the input bearing bore

    -New case cost $850 from us, maybe more or less used.

    Finally, buy driveshafts.

    There you go, the instant road to happiness!

    Thanks Stephen!
    I have a battle post going comparing the Doubler with the Atlas &amp; KluneV.
    Care to add any thoughts?
    I am 90% leaning tward your Doubler. For 1 basic reason, you have always been very cool to me and givin me the time to answer my dumb ass questions. Hell you even took the time at Moab to stop and BS with us (Nor Cal gang) while forging your way to the Gold Bar Rim trail. At a high rate of speed I might add /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif very cool. You looked like one of thoes Ivan Stuart trophy trucks blasting accross Baja /forums/images/graemlins/thumb.gif!
    Your customer service IS what puts you above ALL the rest!!
    So can I get you to call my wife and explain to her why i NEED thease parts? hehehehee J/K
