Greetings,
Locate a Star Parts List. Item #67U is a bushing that allows a rimmed case to drop though the base into a collection box. For crimping at this station, you need a #68U, Shell Floor Base Plug, which is solid. You must now remove the cartridge manually.
Something I forgot. Your friends machine may be the Progressive, 38 Special only, model. Look at the sizing, powder drop, and seating stations. If there is a small metal strap held on with a small machine screw the machine would be a Universal, which is convertible to other calibers.
Nonetheless, myself, or one of the other forum members, should be able to machine/supply you with needed parts.
Cheers,
Dave
