2 years too late, but those tailights are buick riviera 64-64, i think. popular thing to do to vettes at the time.
If you are talking the 61 green vette at post 45, they are 63 Dodge 330/440 lights. I cut them in, in 1967. If it is the red 1000 HP 62, also the same lights I cut in.
Couple of 62s although I do not believe either ran gas. Midwest ran modified sports and the yellow car ran altered. Still both great looking cars in my opinion.
