Ok I have an 83 2wd burb that is soon going to be 4wd. I have read the 4wd conversions and answered alot of my questions on the procedure but I still have some others that wernt covered. I want to make the swap a two or three weekend project because it is a daily driver, I was thinking that I could remove the 2wd parts and install the solid axle and items to get drivable and leave the tranny/tcase and drive shafts for another weekend. I am wondering if I could leave the 2wd crossmember in until later or am I going to have problems with axle contact? The other is can I remove the crossmember w/o having to completly remove the motor or can I just lift and block up the motor? I have the donor and it looks to be pretty straight forward of a swap.
