This looks like a late 80s Bobcat racing body with that extra wide rim around the back.  However, I don’t think any Bobcat bodies came with stock looking steps.  This one is unusual.

“I have a white jeep cj-2a fiberglass tub with the fenders. The brake lights are in and may work. as well as the heater. Body has some minor damage from moving around. As you know, fiberglass is very easy to repair. I’m asking $800.00 obo. . I’m selling to pay for an engine for my xr650l. The only things I’m willing to trade for is another xr650l engine, bike, or a rebuild trade. send me an email or call during the day at nine one four,three one eight,one eight two seven. This thing isn’t perfect, but will dress up that rusted out jeep of yours. And make it lighter.I can email you some pics. I can also deliver it to you within reason.( just help with gas)”
