alex's72fgmc Posted August 31, 2007 Share Posted August 31, 2007 motor mounts, coil springs in front and rear, drill a few holes in frame to slide back the trans cross member, cut drive shaft, relocate proportioning valve to the top of the frame versus the inside for clearance for headers and to eliminate brake fade. possibly diff size brake booster as well but not sure on that one. and some other stuff but not sure what your trans comes with in the box...
