I've owned the car since purchasing it at suction when it had 47k miles. Mileage is now 115k. The car is very clean but the rear end has recently started poping (it has a posi diff). I assume I'm a victum of the defective diff gasket. I changed the diff fluid but issue is still there. Car has a standard white ext/ blue int, has cut out for spot and push bumpers which I have. Passanger front fender needs repair/replaced as I hooked it one of those gas pump protection post. I've always replaced any parts with GM/AC Delco parts (car has new AC/Delco H2o pump) and used mobile 1 full syn with oil changes. Paint is in good condition. Car has zero rust as it was a Texas car before moving to Oklahoma. I've all records for the car since new. If not for the diff issue I'm thinking around $2k would be fair. Please let me know your thoughts as to what would be a fair asking price given the rear end issue.
