speedo gear

thre are several unfortunately. they go by color and it depends on tire size/axle ratio, etc. it also depends on what gear is in the trans, teeth wise.

well that didnt help me at all. i knew that,i thought you could or would tell me wich one.

you are going to have to try trial and error. we have no idea what the axle ratio is nor tire size nor how many teeth are in the current trans including the one on the output shaft. that info is long gone, but you might try on the internet by typing in 62 chev speedometer gear and see what you come up with. there may be a chart out there that has a listing. then all you need is to find the proper gear.

after researching this online i went to classicchevrolet truck parts and found that they ;have 3 different gears. A green, yellow and gray. but they give no gear ratios or tire sizes. they use them in the powerglide and thm 350 as well. the listing was from 63-70, no 62. if you know an engineer they can figure out mathmatically which gear you need. but you need to know tire size, meaning size as well as diameter. Plus gear ratio of rear end,and how many teeth are on the output shaft. I'm sure if you hunton the internet at these classic places they may list other gears as well.
