    Is the Gen. I coming back? Or do you still have them available?

    I want the Gen. I to run on my 465 in my '82 K30. I want the added length of the whole shebang to compensate for the driveshaft angles.

    I have everything pretty much covered except for the 203 input shaft, which I was planning on buying from ORD.

    So, are the Gen. I still available or coming back?

    Please, pretty please, does anybody know the answer to this seemingly simple question? &lt;img src="http://coloradok5.com/forums/images/icons/frown.gif"&gt;

    Wes,

    Not sure if you looked in the "For Sale" section yet......but there is a Gen1 Kit for the 465 in there.....I think it's "Russ" that's selling it. At a discount too!!!! [​IMG]

    I saw that thread. Unfortunately, I already have most of the stuff needed to complete the Doubler, except for the Doubler kit itself.

    I don't want to spend more dough and have more parts laying around. [​IMG]

    I don't have any current plans to bring back the GEN1 at this point. It's not ruled out for sure though. The problem is that with the GEN2, the gen 1 isn't very popular.
    How about just using the NP208 adapter housing behind the 465 and using the GEN2? That gets you another 4" of front driveshaft past our shortest configuration. Would that be enough? You're talking about being 10" or so longer than stock then.

    That sounds tempting to use the 208 adaptor, but which one would I need? What about the 465 and the spline count and shaft length?

    I have pretty much everything to do the Gen. I Doubler for the 10 spline set up. Just need your "go ahead" to make some more Gen. I kits. I'm pretty sure you could find others interested in these Gen. I's again, too. [​IMG]

    I would be interestedin the gen I, in the near future of course. if not what do I modify on the 203 or 205 to use the 208 adapter.

    Wes,
    I Just bolted up a 400 version 203 to my 32 spline 465 with the 241 adapter that came in my 90 Blazer. You have to mill down the 203 front input bearing retainer 4 thousandths so that it will fit into the 208/241 adapter. That centers the shaft, then have the 203 case drilled and tapped (6 holes) for the adapter and it bolts right up. You could even do a custom rotation on it if you wanted. All of the holes are still in the thick portion of the case.
    The 203 box will not fit up flush to the adapter until you mill down the bearing retainer, so it appears that the 465 shaft is too long, but the shaft actually slides all the way in the 203 input gear just like it was made for it once the bearing retainer is cut down.
    There will be other things to deal with, like shifters, as the range box is now another 4 1/4 inches farther back than with the 465 to 203 adapter. Also some kind of a cap will have to be fabricated to cover the 203 idler gear? shaft and keep it from rotating. But that should all be relatively easy. I have not ran this yet, I am still asembling everything (still have to get the Gen2 doubler adapter and convert my 205 to a 400 version) but it all looks like it will work. I think that it will only wind up about an inch longer than the Gen1 doubler that I have in there now, but will make the front driveshaft about 4 inches longer.

    32 spline 465? Is there such a beast, or did you have a custom output shaft made?

    All the 465's that had a 208 or 241 mated to them are 32 spline. I believe they started in the early 80's. It has a long output shaft and adapter.

    32 spline started in 81 with the intro of the NP 208...had one and gave it away before I knew about the 32 spline part.[​IMG]

    Hmmm, I like it. Unfortunate about the long output shaft part. I've got visions of a TH400 backed by a 32 spline input (custom) 465 backed by a 32 spline 205. Oh yeah! Talk about options, including a crawl ratio down in the mid 100s IF you wanted it.

    Hey Wes, there's a couple more inches for your front drive shaft!

    How about a custom planetary reduction of the back of a NV4500 (241 planetary in a custom housing) then into a 32 spline 205? 153:1 with 5.13's[​IMG]

    That is my current project...should be 8" longer than the SM465/205 I have now.

    Russ, so if I get a 465 and adaptor that is the 32 spline and was mated to a 208 t-case, all I have to do is redrill new holes on the 400-version 203 range box housing? I won't need to do anything to the 465 output shaft, correct?

    TH400, 465, 205, 4.56 = 146.63 in low! [​IMG]

    And that doesn't include the converter multiplication! Now, that ratio is getting really ridiculous, especially with an automatic, but, isn't it nice to know you have the option? Most of the time I would be using 2, 3, or 4 but you never know! [​IMG]

    Stephen, would it be possible to use the 32 spline 465 and machine the output shaft to the proper length IF I was to use the 465/203 adaptor and a 32 spline input 203 range box?

    This way I can have the strongest available 465/203/205 set up ALL with 32 splines.

    Wes,
    I did not have to do anything to the output shaft. It fit with full spline contact using the 241 adapter. I believe the 241 and 208 adapter are the same, but I don't have one from a 208 to verify that.
    The only other thing besides having the case drilled was to cut down that bearing retainer. The whole thing took a local engine rebuild shop here only about an hour to complete. It really is pretty simple.

    why do you need a longer front shaft?
    are you doing a 44" tire truck with tons o lift?

    thank you for the info Russ , wish i had seen it a long time ago
