I,m trying to find out about the rear bumber on a 1975 coupe the rear bumber is all one peice from the T Tops back . it also has a molded fin or spoiler all one piece.I would like to make an offer on this car but I,m not sure what to make of this..is it original...aftermarket....hideing somthing?? IT will affect my offer.I,m new to this so any help would be apreacitated.

If there is no seam around the bumper cap then it has been blended and the car did not have a fin / spoiler from the factory.

A popular mod when replacing a cracked factory bumper cap is to blend the seam and if adding a spoiler, to blend that in as well.

Just do a Google Image search for 'seamless bumper 1975 corvette' and see if any of the images match what you're interested in buying.

BTW - A seamless bumper and spoiler, if done right at a real body shop...would cost a descent amount. Personally, I think they look better too...but it's not factory if that's what you're wanting.

Hi they moved your question to another thread in the C3 restoration forum. Look for answers there....and you have some posts to look at...welcome to the Guru!
