got a 70 z28, 3.73 gears and 235/60r15's anyone know te correct speedo tooth gear? Thanks yall

 

Muncie right? http://www.thegearbox.org/catalog/it...82/3697857.htm

 

yes sir.. Nothin but the best for the Z

 

Right on. For the right replacement driven gear you'll need to find out what the drive gear tooth number is, otherwise it'll be a shot in the dark for accuracy.
I just replaced the drive gear in my super T10, originally it had a 7 tooth but the new one was an 8 tooth so it's a bit off since I need to replace the driven gear.

 

so the drive gear is the gear that turns the speedo gear right? If so, it's 6 or 7. Gonna grab the 18 and 21 gear and try em out when she's back on the road. Came 4spd from the factory but PO put in th350. Stuffed a m22 back under it. Can't find a damn starter for it though. Mexico block and the only starter I can find is for a 168 tooth flywheel. That don't work with what I got. If I swap to a 168 then I would need a different bell housing. F-that. Gonna drill the block out

 

thanks so much for the site and info....

 

Yup, drive gear is the one on the main shaft that turns the driven gear. The site's pretty good I've ordered stuff from them before. As for your starter are you going stock or after market? I'm guessing what your having the issue's with is the bolts lining up?
Idk about a muncie but on my ST10 when the drive shaft end is out I could take a flashlight and look through the tail shaft and see the drive gear. You might try that so you can figure out if it's a 6 or 7 tooth.
