I have been in the works of preparing for fabbin up some new sliders and new stinger to add to my bumper. As me and my neighbor were talking we started to wonder if you could built up a good auto in my 85. He has a 85 pickup with a doubled t case. So instead of going through the hassle of doing a conversion to double is it possible to put some higher gears like 4.7's? Also i tore out my rear seat in my runner if anyone has buckets in the rear or anything custom like that please post pics
