Last pair i got from the dealer. They were cheaper than online at transmissioncenter.net or tciauto.com The dealer might not be too helpful though unless you can give them application specific needs, rather than tooth count/gear color. The ones i got were for an 84 C10 700r4 i was working on. The rebuilders in this area don't seem very helpful unless you have them do the work. I'll probably get my 200-4r gears from transmissioncenter.

Gentlemen, This brings up a good question for me...I switched from a 2.78 open to a 3.42 posi, and now my speedo's off (but I don't regret it for a minute  ) I have a 4 speed M22, but originally had an automatic years before I bought the car. What needs to change? The trans gear? Sorry for my ignorance here, but I would like to know how fast I am going, so I can abide by the law of course. Any help is appreciated.

Go to a Chevy/Pontiac parts desk- order (gear 003860346) about $8. Follow the speedo cable to the trans ,the gear is held in by a 3/8 bolt. and their ya go! MIK

Thanks Mik,
Sounds like a plan. Can you tell me how you derived this? And how many teeth on the gear? vs. what I have today?

Cant count teeth, its installed.I went from a 3sp auto to a m-22 Ive got the same rear/trans combo as you. If you can find a good man at the parts counter he can translate rear ratio/ tire dia = part # for you,it wont be on the computer its in the old parts book most parts guys dont want to bother! Good Luck-MIK
