Gas Tank Neck Question
I have a gas cap for a 1969 K20 that has a short clasp and one for a 1971 that is much deeper to tighten up. Can anybody tell me when GM changed the depth of the fill next lip and what years I can expect to find each on?

Re: Gas Tank Neck Question
Difference is 1967 to 1970 were vented caps and the 1971 to 1972 have a non-vented cap due to the EEC system installed.
