I replaced mine on my 96 with the identical ones the factory used. A few years and they are starting to do the same thing the originals did(heat up in the middle/melting the plastic/yellowing). I believe LMC truck still sells them. If you want quality housings/lens/bulbs(focused beam) you won't find them on ebay. Well you may but you need a specific search. You will have to retrofit them to the oem brackets. I'm sure there are plenty of different ones that will work I found these in a google search. Unfortunately the aftermarket forgets about 20 year old vehicles so no direct fit ones.
