Do you think I should be safe leaving the ceramic bodied caps there? They are not original, as the parts list specifies paper/wax where they are.
Flat ceramic disc caps are usually best to leave unless tested defective, BUT tubular ceramic bodied caps (as the last picture on the last page shows) should always be changed.
Disc ceramics use ceramic dielectric and rarely fail. Tubular ceramic caps usually are paper dielectric and are VERY high failure. Paper dielectric capacitors are not just paper/cardboard tubes they were sold in plastic shells (I see some in your pictures too), ceramic shells and metal shells....No matter the shell material paper dielectric capacitors are BAD and should be changed.

The plastic shell caps and ceramic shell paper caps are known to explode when they overheat.
