The old ones, 62 and prior, will take an 11 inch clutch, but they are mostly cast iron open bottom. You dont want a 63 because your m22 wont fit into the opening for the retainer. I have a cast iron in mine with an 11 inch clutch and a late 60s flywheel. The 62 and prior flywheels were 168 tooth and will take a 10.5 inch clutch. Same bolt pattern as a 10 inch

Chevrolet truck bell housings are 11". I used one in my '66 Acadian, works well and they are cheap and plentiful1 '
When closed bottom aluminum for trucks, these are the later years (70's +?) and have a bump in the bottom. Some also have a larger opening for the transmission front retainer and you have to shim them to use with a M22.
If you are not looking for "numbers matching", I'd find a 55-62 cast iron open bottom BH with the starter mount, some have side mounts. They are cheap and easy to find and I think still work fine with a block mounted starter and a 153 tooth flywheel. Any 153 tooth and 168 tooth flywheel will take a 10.5 inch clutch and PP and if you use this with a 168 tooth, you can use the BH starter mount and never have to worry about starter alignment/shims.

The 62 or 63 409 had an aluminum open bottom, worth finding the numbers on this one. Other than that, it may be a truck.

That's worth money to a "correct" 409 guy. Post on 348-409 and ask what its worth. Clean it up and take a pic.
