i have a 1965 chevrolet super sport that previously had a 327 engine, but was changed over to a 350, 4 bolt main, that came from a c 20 chevrolet truck, i need to find out what kind of flywheel cover will fit this 350 engine, with a 2 speed powerglide transmission hooked up together, i tried one from a 1964 with a 283 engine, and it wouldn't fit, so i am hoping to find out what i need , thank you.
