thanks Andice I found this info on
http://www.oldchevytrucks.com/blog/i...hting-1955-66/
looks like i have 66 fender on my 64!
Hope I dont get in trouble for sharing it here!
"The rear stepside fenders on the 1955 through 1966 are usually considered the same. The reproductions on both metal and fiberglass are listed in catalogs and related advertisements as being identical on the right and identical on the left.
Not true if you are a perfectionist! In 1966 Federal automotive regulation required all cars and light trucks to have back-up lights. Thus, GM modified this fender with a stamped indention to better fit the required back-up light assembly"
Anybody with a 66 want to trade driver side fenders???
