The Stovebolt Site Forums The Shop Area General Truck Talk correct spot lights

hello every one, can somebody school me on what the correct GM Guide spotlights are for a 54 chevy 3100. i've heard S-18's, and at the same time, that their for 53 trucks. just want to get the right ones.
thanks in advance.

I have a GM Unity S6 for my 54 3100. It came off a 54 GMC 1/2 ton, I don't know if Chevy used a different light than the GMC's.

thanks for the heads up, the unity spots are nice, i think they have a shorter handle.
