A833 overdrive V8 bellhousing?

Opening up the bell housing can get into the fork pivot mounting holes.

Turning down the bearing retainer can get into the mounting bolt holes for that.

Depends on exactly what you have and the measurements and bolt locations of the above.

I've heard of swapping the retainer, bit IIRC that only works with certain bolt patterns.

I know it can be done, as I have an iron BB bell mated to an OD.

No idea what parts they are or what got machined if anything, as I'm not about to take it apart unless I need to.
