I had this set of T3 headlights (2 two prong and 2 three prong) sitting wrapped up in a box in my garage to go on my Buick - but Jason Cook educated me this Thursday on the 1972 only T3 lights which have a different design. I was told these were working lights but I never installed them so cannot garantee them. The headlight rings and screws are included. You could certainly use them on a '72 Buick but they will look correct for '71 and before. $40 shipped in the U.S. - Paypal only as I have to pay off a large purchase.
Hi Ron, I just PMed you with my Paypal ID - PM me back with your address and I'll make a label for the package so it can ship out on Tuesday.
