This is probably a bumb question, but I'm stumpted! I recently bought a 1984 5.7L Corvette with a massive oil leak. I soon discovered that the hoses on a after market oil cooler was the problem. The cooler was also damaged and leaking so I removed it along with an adapter. However, when I tried to spin on a stock filter, their was not enough threaded pipe on the block. My question is do I have to get a stock adapter. I'm trying to learn as I go and would appreciate any help.
