If the rust is as light as claimed, this early CJ-5 could be worth a look. Has a Kelly hardtop.

“Lots of new parts and recent work done. Very little rust, only on surface. Have service records of over $3500 worth of work done. Motor runs great! Hydraulic plow works and pushes snow well. Will remove at buyers request.”
