...So . . . Are there Chevy-matching bellhousings for Detroit Diesels? Or are the blocks somewhat standardized as far as bolt patterns, etc.? I'd never do this, personally - I'm not a diesel guy - but, it always interests me . . .

Yes, I have a flywheel and bell-housing set for an inline 53 series engine that uses the angled rear engine/transmission mounts found on many Chevy trucks after about 54 or so. It also accepts the normal Chevy 4 speeds and some small Spicer transmissions.
This is not a rare housing, but somewhat difficult to find.
Otherwise, the flywheel housings are round SAE style, and are easy to adapt most any transmission you could want, the exceptions being transmissions with integral bell-housings that are not SAE, often possible but not as easy.
