    I'm pllaing to swap my 32 spline input into a ford case, They will swap without boring the case, correct?

    Reason is, I'm planning to swap in a Ford RC D60, but keep the chev outers. Allows, gear chage without changing the carrier, better driveline angles, and a NP203 clocked flat with the shifter facing up rather than down.

    Oh, and the Ford 205 has a 32 spline output already in it. Easy swap really. I need some 1/2" offset busings for the springs.

    Can anyone give me a reason not to? It essentially costs me nothing, other than time to swap the parts.

    Taken from Offroad Designs website:

    "Convering the input of the NP205 to 32 spline has become very important with the GEN2 Doubler™ kit since the Doubler™ requires a 32 spline input. This details the process:
    First the basics, the 205 cast iron case came with 2 different input bearing diameters, one is about 3 1/8" diameter, the other is about 3 1/2" diameter. The "small hole" 205 case is used with male input gears, examples being the 10 spline and 27 spline. The "big hole" case is used with female input gears, examples being the GM 32 spline and the Ford 31 spline. The photo below shows the 32 spline input with it's input bearing and the 10 spline male input with it's smaller input bearing. There's a pretty noticible difference between the two, they measure about 3/8" difference."

    Are you still running a T400?
    I am curious how you will rotate/flip the 203 since the T400's rear bolt pattern is not symetrical???

    I read their website too, couldn't see the correct info for lookin'

    Thanks for holding my hand /forums/images/graemlins/wink.gif

    I make my own factory Trans and t case adaptors. I buy every adaptor I can find, and I have them digitally mapped out so I have a database of all the trans and T case patterns. I just machine my own Th400 -> Np203 Adaptor. Even has mounts on the side /forums/images/graemlins/wink.gif

    It's all on autocad, and all MINE /forums/images/graemlins/thumb.gif

    Same goes for my NP203 -> Np205 adaptor, clocked up flat, using my own billet plates. I'll throw some pics onto the board when it's all bolted together. I already have my 32 spline shaft's cut, and already have the 32 spline 205, so I might as well use the biggest strongest possible.

    Simple As Pie. The Best Of Both Chev And F*rd.

    Kyle, that sounds kicka$$!

    Any chance of selling me an adaptor or 2?

    I'd like to do an inverted GM 203 on the back of a T400...then mated to a Ford 205 (with the 32 sp input) and clocked flat.

    I already have the T400, 203 (32 sp), GM 205 (32 sp) and Ford 205.
    I just need to be able to hook them together!

    Of course, that's the "wet dream"...
