    the easiest way is get the short adapter shaft for the 700r4 from advanced adapters. Have it installed in the trans then the back of the 700r4 is the same as the th350. Move the crossmember back 2 inches, lengthen the front shaft, shorten the rear shaft and your done. You have to use 1310 cv joint on the front shaft to clear the trans pan. If you want bigger ujoints use the stock 4x4 output shaft on the 700r4 and get the spacer adapter to go between it and the 205. It makes the drivetrain 2 or 3 inches longer and gives a little more room for the cv joint in the front shaft.
