It sounds like plenty have been done to this jeep.

“This was my winter project. I was going to keep it but, with Jeep offering such good deals on new jeeps, prehaps a new jeep? A TON of work was done by the previous owner, I got it and finished it. All work was professionally done.
It has a new steel body on it, (the fuel filler is in the drivers rear instead of under the drivers seat), just repainted, (it was scratched, no body filler plates)
6 point full roll cage.New fuel tank with “skid pan”.  Electric fuel pump.V-6 motor with low mileage, (no gunk under valve covers or timing chain cover) good oil PSI
New timing chain and gears.  “Hooker” wheel well headers with “Turbo” welded mufflers, (as well as a spare set of small “Cherry bomb” mufflers).  “Moroso” chrome valve covers. Almn. Radiator.  New T-90 3 speed trans, Dana 18 transfer case, clutch, pressure plate, throw out bearing.  “Advanced Adpter” chain clutch linkage. Dana 44 rear axle, Dana 27 front axle, (all axle seals were replaced, new fluids in everything underneath, bearing repacked). New brake lines, wheel cylinders, dual master cylinder. New tires on stell spoked rims as well as a spare set of “Mickey Thompson” L-60 tires on “Eagle Alloy” rims. New gauges, Radio, C.B.
Custom Racing seats.  Everything on the Jeep works as it should. It’s not show restored, but a solid jeep.  All it needs is a top and a heater to finish it off. I’ve got all the reciepts for the work I’ve done, as well as as much info as I could on the jeep, plus a list of part vendors.”
