Be expensive, I think. You'd need a new chassis, battery trays, rear brace, rear coupler, body mounts, front and rear arms and dogbones, camber links, steering links, front shock tower, front shocks, possibly rear shocks, rear shock tower, body, pinions and ring gears for front and rear gearboxes. Very little is the same.

You could do a redneck conversion, and just slap truggy tires on a buggy, fab some body mounts, and cut down a real truggy body to make a too-short, too-narrow truggy. Have to gear way down on the pinion though.
