With the AlterKtion K frame, a stock truck oil pan fits just fine, no need for fancy aftermarket pans. It may clear stock K's too but I did not check. I've got a '68 Sport Satelitte convertible in the shop that I'm building right now. 6.1L hemi, truck auto trans, TTI headers (DS needs slight tweaking to clear trans pan) Air Ride all 4 corners and 13" Baer brakes all 4 corners.
