203 with part time kit, does it matter for the doubler?

[GM Man]

Dont know if it matters or not, but I thought I would ask. Would it matter if the 203 I have is part time or not for the ORD doubler?

Thanks,
Travis

it probably wouldn't because the doubler only uses the gear box and the part time kit it for the spider gears is the rear.

nope. all you need is a 32 spline range box.

Thanks for the info. Would a 203 on the back of a turbo 350 be a 32 spline box?

 

[zakk]

no, that would be a 27 spline. TH400 203's are 32 spline, and ORD makes a kit to convert the common 350/203.

Cool, I'll check it out. Thanks for the info. /forums/images/graemlins/laugh.gif

You need 32 spline input NP203 to mate to a TH400 or a 32 spline SM465 but if you're going to a TH350 or TH700 you'll use the 27 spline input. The output of the 203 comes with our kit, that's one of the essential parts to mate to the 205.
