I have been doing a lot of reading over on pirate on this box4rocks thing http://www.pirate4x4.com/forum/showthread.php?t=456669 Right now I have a 32 spline 208 and a 32 spline 241. Looks like he still is not making the kit to work with the 208, but I could use the 231-to241. Now is the 231 trasfer case commonly found in S10 or S15's able to bolt to the back of my TH400? I don't know what trannys came in the little blazers, but if I could get a 231 to work I could get this kit which would only cost $400. Anyone have any good news for me? I believe the 231 is 2.72 low just like the 241. This would be a great inexpensive setup for my rig................. If the 231 has the same bolt patter as all the other NP GM transfer cases it should bolt up after thinking about it. Now getting the 32 spline input shaft might be a chore. I wonder if the 208 input spline or 241 would fit into the 231?
