Has a fiberglass body.

“51 Willy’s Jeep for sale.
Rebuilt engine, new clutch.
Fiberglass body with new ragtop.
Brand new tires.
Runs and drives great.
It doesn’t have a lot of top speed because of the low gear ratio.
These jeeps were geared very low for the military. Top speed is probably about 50 mph.
I owned one several years ago just like it. To get more MPH, I put bigger, taller tires on it, to compensate for the low gear ratio. Trust me, it has ample power to turn bigger tires. Lots of power for a 4 cylinder.
Asking $5,500 or best, or trade up or down for 1972 or older muscle car. Call – do not text.”
