 I recall seeing the 400 fender emblems on early 70's GM pickups but not the 402 which is not to say that they didn't exist. My general knowledge of these trucks is limited, but I can tell you a whole lot about a certain 1972 GMC C1500 Custom that I've massaged for the last 5 years.

Thanks for the info. I had someone tell me that it should say 400 not 402. It really does look factory to me though. Joe

Hey, there are no 402 badges that I know of,402 BBC's were called 400 ci invaders in GMC trucks, Look for a stamped code on the block and trace it through a hollander's manual for correct year and appl., also check your VIN# sometimes they say what came in them although a lot of times it just says V-8. also check in your glove box door. The Badges you have sound correct.
