| Post subject: | 3.23 gears for 7.25 |
My question concerns the interchangability (is that a word?) of the gears from a pre '70's 7.25 to a 1980 7.25 rear end. The following is copied from a July 2001 message: ----- ": Can 3.23 gears from an A-body 7 & 1/4 rear Quote:
: diff be installed into an F-body 7 & 1/4 : rear diff? I would think that they probably : would, but I don't know for sure, and I hate : to assume. : : If someone would let me know, I would : appreciate it. The year(s) are important here. All "early" 7 1/4s used pinion "shims" where "later" ones used a crush sleeve and carrier bearing "adjuster rings". (started in 1970??) For an easy gear swap, you want to use the gears designed for the housing set-up you have. DD " ----- Does this mean swapping pre '70's 3.23 gears into my '80 rear would be impossible or just difficult? bmazur@canada.com |

Difficult because you would have to find (make) all the needed shims to get the mesh set correctly. Realize that it's been 30+ years now on a rearend that was not "liked" by most everyone. Can you say "hard to find parts"?? When it comes to rearends it's much better / cheaper to find the ratio you want in an assembled unit and swap the entire assembly. DD |
