been searching the archived posts, but still need answers. looking for a 700r4 to hook up to an early 205 off a th350. i have the adapter and sleeve and will get an output shaft from ORD. is there a difference between the 2wd and 4wd cases like the th400? is there any benifits to spending the extra dough on an '88-'91 that i can't get by getting an '86-'87 and upgrading when i build it? been getting conflicting info from junkyards, trans shops, friends, etc. i'm looking to do the swap on the cheap(not going to happen) so i'm looking for the best year to get a buildable core from a yard or someone parting out.
