Rupp Chaparral Enduro?

[Ludovico Prelogar]

I've found a Chaparral enduro for sale, and was hoping to get some info on it. its only the frame, but have heard it may be a low production kart. its missing the steering hoop but looks like they were bolted to the frame for raising or lowering the steering hoop?

Thanks!

Here is a frame just like the one for sale, it is just missing everything.

Both pictures were taken from OMB.
