I have an 89 s10 4 wheel drive extended cab, I was planning on putting a 350 in it but the stock oil pan will not work with the 4 wheel drive and im too cheap to buy the conversion one So my question is what would it take to convert my truck to 2 wheel drive? Would the tranny i have still work? does the transfer case unbolt from the back of the tranny? what about the control arms? 2 wheel drive control arms work?
