Rapid-Air, Air-press Feeder, Unknown model, for parts or repair

Rapid-Air, Air-press Feeder, Unknown model, for parts or repair. This feeder has been taken apart and needs to be repaired or can be used for parts. Where the side mounts connect, the hole for the screw doesn't lineup properly so when you go to screw in you bolt it doesn't lineup. Note, the item in the last picture is NOT included.

Forgot to remove this when taking pics, it goes w/ a different unit I also have available here. Any questions contact me and I'll do my best to help.
