And I am trying to see if I can get a capacitor list around and one capacitor I have a question about is the motor run capacitor that was used to get the motor for the tuner section to work, its a 70 MF 24 VAC capacitor that's in a cardboard tube but I'm not sure where I would locate a capacitor like that anymore, most of the motor run capacitors made nowadays are rectangular shaped.

That type of cap was used in Alliance Tenna rotor control boxes, that may work. I have an older Motorola model 12Y, similar tuning drive. It worked well long ago when I got it, the tuning motor/presets always worked, never recapped but not restored either.
Good luck, that is a beast with the PP 41's and dual rectifiers, it will sound incredible. I love seeing a console Motorola of this vintage as they seem to be pretty rare.
Caution: rubber parts in the tuning drive system (to keep it quiet) may be worn out, mine was slipping last I tried it.
