He also sent me some pics, if you want I can email them to you or post them somewhere.

You can post them here if you like, I am uncertain why you would want a 5sp transmission when the 4 speed is likely fine, also something important, what voltage was his car?
When I did the calculations for the stock differential and transmission for a daihatsu move (aka 4sp) with my stock 48v motor. I came up with a top theoretical speed of about 52mph in 4th - losses or about 45mph. Apparently a 5sp ends up at about the same final drive ratio as the 4sp. The odd part is his comment about 4th gear, folks with a 72v miles typically can get up to about 40-45mph in 3rd gear of the stock 4sp transmission from china.
I can only guess he has a 48v car and his final drive ratio is the same on the 5sp as on the 4sp apparently.
If you can PM or Email me some pics / info along with this gentlemans contact I would like to speak with him. Oh and make sure he knows,
High gearing + field weakening = disaster. Field weakening is good when you need to rev the motor up to a higher RPM under a moderately light load, under heavy loads its just a bad idea. He would definately need an accurate ammeter to see what is going on, likely 5th is overampping his motor a bit already.
