They were also used on 3.73 cars. I had one on my 71 Z28 M22 car I bought in 1975.

Re: 1970 M22 speedometer reduction box
 

The .8241 is the ratio of this reduction box... I know that 1970 LS-6 M-22 used this ratio with 4.10 gears and 14" rims...
I have a large assortment of these with 6 or 7 different ratio's
I will be at the reunion July 27-28 if anyone want to see them... Crash
