Early 60’s EzGo

[Gunner7800]

I recently acquired an electric ezgo from an uncle that passed. I’d like to restore it but I’m needing some direction. My best guess is it’s 1962-1964 and I’m unsure of the model. I’d like to find a manual for it and some direction/suggestions to find parts. It has a 36V motor that works however, I’m not sure if it works properly. I’d like to use lithium batteries when finished. My experience is with gas carts and I know very little about electrics. Due to the condition this is going to be a substantial project but I’m in no hurry to complete. Any help is greatly appreciated.
