Upgrading a Club Car Resistor Golf Cart to Controller

[ACEGOLFCARTGUY]

I'm upgrading a 1989 Club Car 36 volt resistor golf cart to a Curtis 48 volt controller. I have a few questions for you guys before ordering the parts. Anyone know where I can find a 5k-0 curtis style pot box? I really dont want to mess with the Club Car MCOR throttle.

Heres my shopping list so far to do the upgrade. Do I need to change/add anything?
6 8 volt batteries
controller
charger
5k-0 pot box
48 volt contactor
precharge resistor & diode
4ga welding cable

Thank you!!

Errr it didn't take much to convince myself but now I figure why not go to 72 volts? I want to make this cart street legal to ride around town. Being able to stay out of the way of angry drivers would be really nice and thats why I'm considering the upgrade.

New shopping list:
9 8 volt batteries
72 volt 300 amp Kelly controller (too low amperage?)
72 volt charger
0-5k pot box
72 volt contactor
precharge resistor & diode
4ga welding cable
heavy duty F/R switch (where do you find these things?)
