I know some of ya'll on here have already done this. OK, This is what I have. I will be running a 400 SBC, Turbo 350 tranny. I have a 27 spline input 205 T/C. How do I do a 203 to 205 doubler? I have built a lot of s**t. But, I am clueless on this. What parts I will need. Where to get them. Do you have some of the parts I need 4 sale? You have to spell it out for me!

Thanks, Don

Go to the offroad design website, they have a pretty detailed account on what needs to be done.

You'll need a 203 box, 203 to th350 adaptor, shifters...with some research, you can decide who's doubler adaptor to run. Off the top of my head...

1) Do you have any pics of the setup?
2) How long is it from the tranny mounting surface to the center of the rear yoke?
3) Could the input be changed to the 27spline with the TH350 front adapter?
4) How much?

You can PM me the price if you want to!
