Did some of the high hump install today. I cut out the old one and have the holes drilled for the mounting bolts. I ordered some 5/16" threaded square nuts to weld on the underside so it will be like a stock install. Once those are in and the bolts tightened, I will spot weld the forward firewall mating section in. I am transferring the gas pedal stud mount over from the low hump as the high hump had 1/4" nuts for the pedal studs and my stock low hump pedal mount studs are 5/16" thread. Pictures below:
