thanks for the link troy and i hadnt thought about the crossmember, but it looks like if i go find a 6in tail shaft for a th350 at the junkyard then i will be set for lenght, seeing as the 200r and 350 (with 6 in tailshaft) are both 27 and 11/16 in. I'm not sure about the crossmemeber locations though

edit,it looks like i am going to have to move the crossmemeber regardless, towards the front about 7in.
