67-79 3 wheeler need help please.

[Kansas Transit]

Hello all, so glad to find this place, any help would be appreciated. Picked up an old EZ go 3 wheeler from what I can tell it's of the 67-79 variety, can't find a serial number and there is no motor in the cart, but hey it was a 100.00, lol

Questions, cheapest way to repower this, and I noticed this has a rear drive pulley that is mounted right off of the rear axle where a pinon yoke would be on a car, IOW it is basically sideways, is it possible to use this rear with a repower or would a guy be better off with a newer style rear with the pulley groove facing forward??

Thx all,
