a833 overdrive bellhousing

Actually, they are the most plentiful in terms of factory production. The 5.125" bellhousing was the only bellhousing produced by chrysler for the OD, as that was the only factory bearing retainer size for the OD. Any OD with a different size bearing retainer than 5.125" has been modified.

I find that very interesting, since they used the 833 behind the small block from 64 up, and the OD didn't come out until 75. So that would be 11 years of production.

Do you have some production numbers you can share with us?
