Believe that the Mor-Ryde suspension, as those pics show, began in 1967
You got a deal if the shell is in as good a shape as it appears.
The rest can be replaced!
Mine is a T-27, but............
Link to my 1966
(DMV title and data plate shows '66 - link states '65) T-27 renovation pics:
The battery box on the front originally had a F3-ET sized battery in it - like this:
Exide Heavy-Duty Farm Battery, F3ET - Tractor Supply Co.
The battery box only had a few wires that ran into the front curbside of the coach where the convertor and 12 VDC fusebox was. The 120 VAC fusebox was in the rear streetside.
