So a thread in the for sale section got me thinking since I'm in the process of swapping a 4500 into my 85 k20 to replace the th400. Do the later squares have a removable hump and is there actually a low & high version? If so, what dictates the high vs low: 2wd/4wd or auto/manual? This was obvious on my 69 but I haven't pulled up the floor mat yet to have a look see.
