Ok. That's cool that you're going to resto! So if its not going to get used, reassemble with everything the way it is. I'd prob do bearings still.
A stronger motor was a period correct upgrade too.
That's up to you because it will just be eye candy anyways.
Just don't go crazy in respect that the stock esc's couldn't handle super hot motors without burning up resistors all the time.
The old radios were a weak point also but non-issue on a shelf as well.
I think you're almost set as is!
