I had an issue with a 97 gas tank. The spot where your fuel pump goes had 4 tabs on it where my 86 gas tank had only 3. The issue is now the locking ring. I got my 3 tab locking ring to kinda fit but it isn't tight so there are some fume issues. I wonder if anyone knows how to resolve this. Where can I get a locking ring for a 4 tabbed hole? sorry for stealing the thread.
