833OD bellhousing?
Just a heads up, Brewers has O/D bellhousings, but it is less expensive to have yours cut, locally, as I described, partially through, leaving the engine side of the bell at 4.354" and cutting the bell from the back out to 4.807"
Your other option is to look for a 4.807" or 5.125" bellhousing elsewhere. Most of the ones on ebay that I have seen are either the 4.354" or more expensive than it costs to machine one of them out.
If I were you, I'd save the cash and headache and just take the bell and retainer to a machine shop so they can fit them for you.
