regen or series rebuild?

[indeep]

I have a 2004 club car ds 48v IQ that was involved in a salt water flood. Everything but the chasis and body are toast. I'm doing a total rebuild. I have not purchased a charger yet. I did pick up a new mcor motor and on board computer, also a new solenoid that I assume I will have to replace to upgrade motor. I am lifting the cart 6" and will probably run 10 or 12" tires. It will be used mostly tooling around the campground with some on road and light off road. What would be the most cost effective way to go, Regen or Series. And if I go Series, what changes need to be made? I've noticed none of the high amp altrax controllers seem to have the right plug ins for the factory wiring harness. Do they come with adapters. And lastly, do both types of motor bolt on to the same rear end. I've never done this before, so I may have many more questions.
