hello Ray, we spent a lot of time on general maintenance on this only truck. We removed the automatic transmission and replaced it with a NV3500 5 speed. Searching discontinued parts on ebay and Amazon took some time and i spent a good amount of time on the phone with junkyards / dealers around the country. Replacing old leaking H20 pump,hoses exhaust gaskets, oil cooler lines etc. led to replacing the front main engine crank seal. but my son (and me) learned a lot and made some lasting memories. Surprises like having to rebuild the transfer case (manual trans had a 32 spline output gear and the auto had a 28, or visaversa) added to our eperience and expenses...
my friends hydraulic lift was not available as planned so all of the work was done on our backs in the driveway. Winter caught us so he is driving the 94 Z-71 with the manual trans until spring (hydraulic lift avail) when we strip it down, powdercoat the frame and mount the 95 step side GMC body to the 4x4 frame. A project like this is not economically feasible and it would be cheaper to just buy a 4x4. but if rebuilding a truck that you know inside and out is your goal this will do it. I plan to post some pictures as we proceed.
