I've got a LOT of heat coming into my '46 from a 350 too. But the truck has no shift boot & has an opening for the master cylinder in the floor under the driver's seat.
Based on someone's (?) idea here, I intend to replace the floor "board" someone made it of 1/8" plate (heavy but no rolled edge so it doesn't sit flush with the rest of the floor!) with 1/2" or 3/4" plywood veneered with aluminum or stainless UNDER the floor. Then cover that w/lizard skin or the welding blanket above AND below held on with countersunk screws & fender washers. Same on the toe "board". What is everyone's opinion of these ideas? Too lumpy under carpet? If so, what seems to be THE optimum material/product for the inside below the carpet?
