Hi All!

As an offshoot of this week's Weekly Fun Question, it has come to our attention that the Ford Toploader Close Ratio Transmission (RUG-AW1) was available in the 1971 351 4V Mustangs. Several sources on the "Net" indicate that this was a reality.

This information is at odds with the statistical data published in Marti's "Mustang ...by the Numbers (1967 -1973)" which shows that the 1971 429s were the ONLY Mustangs during the 1971 - 1973 period to receive the close ratio (2.32) gear ratio transmission. According to that Source, all others 4-Speeds received the Wide ratio (2.78) transmission.

I am curious as to whether any of you might have what might be one of the 2.32 Ratio Transmission in your 351 4V 1971 Mustangs (from the Factory).

Thanks!

To add to the above, I believe the transmission code would be 6 on your door sticker if you have the 2.32 ratio transmission.

 
Only the 429 machs? I know they were on BOSS mustangs too (I know you are talking about machs only here).

No, actually according to the reference (Marti's "Mustang...by the Numbers, 1967 - 1973") ALL the Boss 351s came with the wide ratio 4-speed transmission.

I am speaking of ALL the 1971 Mustangs that came with a 4-speed transmission in the post above.

Well I can't really argue your point since my boss came with a wide ratio 4-speed Lol. I figured since everywhere I ever read about the boss 351 said a close ratio was optional.

I learn new things every day.
