patrickt Pat my car is old 428. There is a large plate that goes from the floor of the car on both side to 1/3 of the way up the back inside panel. It screws to the tunnel and back plate. I remove this panel and have access to the brakes and bleeders. Tunnel doesn't have to come out. It's tight and hot when I have been racing but no problem with using small heedle nose visegrips. Lucky.
