1980 Electric E-Z-GO Marathon Problems

I just got a 1980 E-Z-GO Marathon Electric Golf Cart, Unfortunately it is mostly in pieces and needs to be re-assembled. I am figuring it out for the most part, but a manual and/or parts diagram would be awesome. I have also had to dis-assemble the electric motor due to a broken stud on one side of the brushes. Putting it all back together is an issue since the motor has to be assembled in the cart…

Any help or guidance would be very helpful…
