You will need to order parts separately. Don't be afraid to start spraying the hard to reach items with a good quality penetrating oil now......and anti-seize them on re-assembly.
The rubber mounts are an easy fix, and not expensive. The fan is about $290.00 +/-, and the ash tray rollers about $18 each, if necessary. Gaskets are small money.
The roller bearings I have a special connection for, and will PM you with that info. Ashing arm and linkage are a 'repair as necessary' item....as is the linkage to the ash grate.
Your unit may be in great shape anyway, but many used ones need major repair to remain trouble-free for another 30 years. Do you use the tankless coil? If so, did it ever leak?
Those studs are a weak link, which is why i get cranky about the older design of AA, EFM, GJ, Van Wert and even Keystoker.
I do understand the 'stylin' thing of the 50's.....cover it with shiny covers, blah, blah, blah, but what a PITA when the small leak is not detected for years and an expensive repair becomes necessary.......
