Good questions!!
The 1/8” shift is because some 4406 converted trucks get a vibration at 45-65 mph. During several years of research on this I discovered (by learning from others) that the rear driveshaft angles were actually too perfect, adding a little bit of side deflection stops the vibrations
The 5 speed shifter is only poking through the 1” thick heat shield material that is under these tracs and yes it maybe still too close to the floor. I may need to modify the crossmember further. They guy who built the crossmember was using a stock 5.0 mount which is about 1” less in height. He removed 3/4” from the x member usually I remove more to accommodate the poly mount
