I just got a new Summit catalog in the mail and Summit brand gears are $159.95. Isn't there a tag somewhere on my rearend that tells me the gears that are in it from the factory? It has a tall gear in it now but I'm not exactly sure which ones. I am leaning toward buying a 3.73 gear for it but need to know what carrier I have. Looks like I can get a 3.73 for either carrier. I was concerned with fuel mileage in a previous post and am not really looking for gears to improve that but don't want it to get much worse either. Are 3.73's good for a cammed 350 in a half ton 86C10 with a 350 and a 700R4 (stock convertor)? I can take the cover off and look or count teeth but I drive it to work every day for the next week. Also, besides gear lube and gasket maker, what else do I need to budget for? Thanks, Scott.
