GM changed the length of the transfer case to transmission adaptors to maintain the same overall lengths between the different transmission/transfer case combos for the 67-87 trucks. The rear driveshaft will be different because the square body trucks had a longer wheel base than the 67-72’s. You have a fairly rare combo there that I’m not completely familiar with. That was a 1 to two year combo but I bet the measurements are still very close to 67-72.

That's great to hear, thanks! I got the suburban rear driveshaft because I figured it would be long and I could have it cut it down to the exact length I needed. I went the tbi route because I was able to afford a new crate motor that way and still have fuel injection and overdrive. A new crate LS swap was out of my reach, and I didn't want to buy a used one. My truck will basically be an early 90's computerized OBS truck with a 68 body. Works for me!
