Build it the cheapest way, meaning use what you have. Get it running and driving, then get some miles on it. Once you lived with it a while, you can change out what you don't like. Brakes and such, will not be much trouble to change out if you decide to, same with gear ratio's. Driving 70 mph for hours isn't going to happen, but around town and country highways will be no problem. Carry a few spare parts and nothing will stop you from having a nice days drive.
