Found a Source for 10” rear drums with 1-3/4” shoe
If you need to fit Jeep drums on, you can do it as shown in these photos.
You need longer wheel studs for that. In my case I had SBP centering part, and Jeep drums have LBP centering hole, so also this needed to be addressed.
Its not for everybody and I don't recommend it but as shown here it can be done.
In my case I had this spacer on the outside of the previous drums anyway cause my tires were rubbing.
Its about 7mm thick.
