Time to fix a bad oil leak on the 65. I checked everything today and the leak is eith at the rear seal or the rear oil pan gasket on my cobra oil pan. The flex plate and surrounding areas are clean and dry so Im hoping that the rear oil pan gasket is leaking. That being said, does anyone have a gasket they would recommend for the old cobra pan? I think I used a 4 piece gasket when I installed the pan. I would also consider swapping to another pan if you have any recommendations. I bracket race the car but Im not sure that I need the T pan. Also not sure if I need to switch pickup if I switch pan. Anyone use a single piece rubber gasket with aluminum cobra pan?
