Give it a shot.You amy also want to try Ebay.There are some on there cheap for other GM cars (Chevelle and Camaro 70/71,etc...) that look similar but i'm not 100% sure if the square mount is the same dimensions as ours.
Mine are not for sale.They have been sitting in the little paper package waiting for me to have the money to finish my car so they can go back on
