    Is there anything preventing me from running a 203 range box with a 32 spline input and a 31 spline (F*rd) output into a Chevy 205 with a F*rd 31 spline input gear?

    nope, nothing wrong with that. thats what i was going to run, but now i found something else

    ford 31spline input is the cheap alternative to the expensive chevy 32spline input

    AFAIK the doubler shaft only comes in a 32 spline. So the Chevy would have to be 32. so yes i think there would be a problem.

    Thanks. Any significant strength differences between the 31 and 32 spline stuff?

    Most companies that make doublers (if not all) have at least 31 and 32 spline intermediate shafts.

    from northwestfab's website:

    On top of our basic kit you will need:

    - 1 NP203 to mate to your transmission
    - 1 NP205 with either a short 32 spline or 31 spline input gear, or a Dana 300.
    - A 2nd crossmember or custom crossmember
    - A means to shift each transfer case from high to low range.
    - Modify your driveshafts to fit new driveline length.

    noob;) :haha:
