I bought this stuff yrs ago to convert my 71 auto to a factory 4 spd. I am not too familiar with the specifics of yr interchange and details such as back up and lock out etc...but I have a picture of all the stuff and some of you guys will know more than me. I have decided not to do the conversion. The M20 trans prob needs rebuild? I paid $2,500 for everything will take $2,000 for everything and will entertain all offers.

 

Do you guys know if this is a close or wide ratio trans?

 

PM sent.

 

Ive been told this is an M20

 

 

... and M20 = wide ratio
M21 = close ratio, and
M22 = close ratio heavy duty.
