    i was reading something somewhere...cant remember where...but i guess thats not important..but it said that you no longer make the kit for the 465...is this true? /forums/images/icons/frown.gif /forums/images/icons/frown.gif /forums/images/icons/crazy.gif i had planned on ordering one sometime this summer but if that is the case may have to figure something else out

    You just get SM465 with a 203 adapter. Put the 203 range box on, the doubler bolts into the range box.

    That's what I am in the middle of doing now...

    Now if only my twin sticks arrive by next week, I will be going to Rubicon!

    Hey I just had a question about the setup,from the factory does the sm465 to np 203 use an adapter sleeve on the output shaft to input shaft or does the sm465 just spline into the np203?Ive got an np203 for the sm465 and the adapter but was wondering if im missing anything here.....
    Where is the usual "wear" on these splines or coupler or whatever they talk about?

    The sm465/203 was a direct male/female coupling, no drive sleeve.
    The wear is typically on the shaft teeth or the input splines but more often on the input female splines. They'll start to look more like this:
    _
    / \

    Rather than this:
    ___
    / \

    A little crude but it's fairly obvious when you look in there. Then it gets sloppy and breaks causing all sorts of grief. we do have new inputs for them if you need one.

    I thought( and I am known for being wrong) but isn't the 465 kit only availible for the 32 spline set up and not the 10 spline??

    I think you are confused between the 203 and the 205.

    The 465/203 connector shaft is 10 spline. You don't touch the doubler yet... Then the doubler shaft and "plate" goes into the gear sets and bolts onto the 203 range box.

    This shaft from ORD is a 32 spline. This goes into the 32 spline 205. Hence the 205 needs to be from a TH400 32 spline version.

    so I am correct( or half right , or way in left field?), the kit is only made to work with a 32 spline set up not the stock 10 spline 465-205, or use a later style 465-205 that has the 32 splines and get a different adaptor made.

    ..just need to find a th400-style 205, LMAO...sure are those under $250 yet???? /forums/images/icons/smirk.gif

    I'll stick to my 465-205 for now.

    Ummm.... sort of..

    The problem is the 465/205 adapter will have to be removed.

    You need a way to connect the 465 203 and the 203

    SO...
    If you have a 465 and 203 setup, you just need to buy the doubler, and a 32 spline 205 (which came from behind a th400), OR have your 205 milled for the larger bearing and buy the 32 spline female input.


    It sounds like you have the factory 465 10 spline, 205 adapter (this mounts to the crossmember), and 205.

    You need a 203 adapter (factory or aftermarket), 203 range box (or whole thing and take it apart) buy the doubler, and have your 205 milled (here in CA ~$100) for the larger bearing and buy the 32 female splined input (ORD ~$150, I think) for your existing 205.

    Basically, you should be able to get this all done for about $1200 + shifters ($170 from ORD).
    $100 for mill work, $150 for 205 input, should be able to find a 203 for $100, and maybe get the 203 adapter for free, or pay another $50.
    Then buy the doubler = $740.
    100+150+100+50+740 = $1150
    Of course, now you need driveshafts too!!! /forums/images/icons/blush.gif

    OK you sort of get it. I'll try a couple ways of explaining it to help clarify (that is my intent anyway)

    The doubler is used to mount a 205 to the ass end of the 203 range box. It does not matter what transmission the 203 is mounted to. Now, the 10 spline vs. 32 spline has to do with the input of the 205 that you want to mount to the out put of the 203 range box. ORD is no longer making a kit to mount a 205 with a ten spline input to anything. So you have to find a 205 with 32 spline input.

    What the 203 input is mounted to is a completely different story. It can be mated to anything (anything, meaning it has no affect on the doubler kit, NOT anything as in, it is possible to just mate it to anything. Which transmission the 203 is stuck to is not going to make a difference about how the doubler will work. It will go to 32 spline 205.

    Now where 10 spline and 32 spline 205's come from...I have no idea since my kookamamy plan involves a Ford 31 spline 205 and a GM 203 and a custom doubler. I know, I'm a freak.

    It's like a one of those dreams that seem more real and memory like than dream like. A dream where I had the money to buy it, but now that I'm awake, I can't find it. /forums/images/icons/confused.gif heheh.

    I think we've come up with a couple different ways of saying the same thing. My attemt to distill:

    NP205 must be 32 spline input. Repeat this 5 times. This 205 type came from behind TH400 transmissions. This is merely the factory application and has nothing to do with anything anymore. With the Doubler, your 205 has nothing to do with the transmission. The NP205 must be 32 spline.......

    The NP203 input must match the transmission you choose. There are many options for this spelled out on our website in the doubler info.

    Hope this helps get everyone on the same page, maybe?

    So you're saying the 205 must be 32 spline? /forums/images/icons/wink.gif /forums/images/icons/grin.gif /forums/images/icons/grin.gif

    I think that if people went to the ORD web site, which is very well written, and read through it several times, and thought about the relationship between mating parts, it would become clear as to what you need to do. It took me several reads to get it right, and now I'm searching for as many factory parts as I can so I can do a doubler too!
