Looking for rebuild advise

The best thing I can tell you is you don;t have enough for a rebuild - but you should have enough for a re-ring deal. Invest in a vernier caliper, a set of micrometers, and a dial bore gage and carefully inspect and check things out per the service manual. Buy the parts you need to replace worn beyond spec stuff, and you should be fine. Slant's generally don't wear too badly unless they were abused.
