I have a 1975 K5 with original panels...I would like to repair or replace some rust area on passenger side..this is my question. Will a body panel from a later year fit on my Blazee? I saw a 1974 Blazer in my area that had the door covering the gas tank opening and I know that wasn't a stock item for that year. So did this person replace with later year and also replace fuel tank neck to fit new opening? Did he have to cut and make fit because of full top and doors? I couldn't find owner to ask questions so I know someone out there must know. I have access to later year panels but ...what year will fit without cutting and patching the panel at door/top area? Thanks in advance.
