I bought a 69 about 4 years ago. I have a 69 with a 396, 4spd. I have bought the car in pieces from my brother, and had all the interior pieces to complete the inside. I installed the new carpet that came with it. I did not use any insulation between the floor pans, and the carpet. I think that the carpet is from JC Whitney, not my first choice, but it came with the car. My 4 speed console gets very hot at the boot also, it also has a new gm boot. I realize the headers are very close to the floor board, and are generating alot of heat. It was just a hair under 80 degrees last Sunday, and it was almost unbearable, the humidity was fairly high also. I'm sure it doesn't help that the car is a dark burgandy. Please help me, I don't have enough money to buy a Vintage Air system, as I am about to have the car painted. The A/C is a project for next year!!!!
