Does anyone have the specs for, or measured the exact specs of the BB shell of an OCC Stingray? Thread size too. I believe the length is 120mm. I'm looking for the OD & ID of the tube and the thread size. Any help is always appreciated! Thanks!
Scwinn OCC BB Shell specs?

It's a regular "English" threaded BB. AKA "British", "BSC", "BSA", and "ISO". But, yeah, the normal threaded 3 piece-type BB shell. 1.375"x 24tpi. Normal BB shells like this are 68mm wide, side-to-side, but the OCC is waaaaaaaaaaaaaay wide to clear the rear tire. I'm not sure about the spindle, but it'd have to be pretty long to clear that goofy rear tire. If you're changing the cranks, the required spindle length will likely change, too. The original BBs had the separate spindle with the caged bearings. Oh, and the drive-side is reverse-threaded, too.
You can find replacement BB sets and spindles on ebay and other spots online.
