Final Tranny Swap ?'s

If I use this crossmember:

http://www.classicparts.com/prodinfo.asp?number=79-507

And a TH350 with a short (READ: 6") tailshaft, it'll work with my stock driveshaft, that was originally hooked up to my 3speed manual? I just want to make sure before I start buying things.

Re: Final Tranny Swap ?'s

The location of the tranny cross has nothing to do with the length of your tranny tail-shaft, only the mount points on the frame. You may have to drill new hole to mount your new crossmember but what you should ask:
Is the Th350 with the 6" tail the same length as stock 3sp? Got a tape measure and both trannys handy?

No, don't have the tranny yet. I need to know the differences because I need to order the th350.

I'm not asking about the location of the crossmember, i'm asking about driveshaft issues.

Re: Final Tranny Swap ?'s

Yes....I did the swap. It is no problem, you can use the 3 speed driveshaft with no mods. providing you get a short tail TH350 to put in it's place.
