`Gears

There’d be several factory gears available, standard or optional?
 
The 2 1973's that I had had 8 3/4's. I just looked in my 1973 Parts Book. NO 9 1/4 rearend's in 1973. 1974 was the first year for the 9 1/4. The people that say they had a 9 1/4 in their 73 really had a 8 1/4.
 
For '73, generally all with trailer package were 8.75". Cars with with 400, 440 and some 360 4BBL were standard with 8.75". 8.25" sstandard with 318 and 360 2BBL. 8.75" was also an option for small block cars if so ordered.

8 3/4" is what it be for the BB cars. That's what's in mine. I don't have the factory towing package so mine is 2.76:1.
 
Here is the rear end chart from the '73 parts book. (Click on mail 0009 not the icon)
