Im going to start upgrading my 91 K5 that I reciently purchased. One of the things that I have noticed that will need to be fixed or modified, is the transfer case crossmember. There is about a 1/4 inch gap between the front drive shaft and the crossmember. It looks to me that the drive shaft would hit the crossmember if the suspension limited out. I know I could put spacers between the crossmember and frame, but I dont want to lose any ground clearence. It has a 4 inch lift on it right now, and I plan to keep it around the same height. Has anybody had this same problem? If so, what did you guys do or would you recomend. Should I "loop or tunnel" my stock crossmember (like this), or should I custom make or have a custom crossmember made? Anybody have pictures of what they did? Thanks for any imput.
