Toyota Land Cruiser FJ40 1971

Land Cruiser will start but runs rough and doesn't idle long enough to drive, though I was able to drive it acouple of years ago.After being started it will occasionally run smooth for a few seconds but will run rough again and then die. It is in need of some attention to get it back in good shape.
My dad bought this Land Cruiser in about 1976 and it was a California car most of it's life. Moved it to New Jersey about 10 years ago but never got it road-worthy again. It's never been driven in winter. Some minor rust in spots on body panels. In last 10 years it has been stored in a garage for about 5 years and in a driveway with a car cover about 5 years. In last 6 years replaced all brake cylinders, drums, master cylinder, and brake vacuum diaphragm. Also had the carburetor rebuilt. It needs new tires. It needs a mechanic to get it running smoothly, I don't know if it is an ignition or fuel problem. It probably needs a new battery also (I've had to jump start it the last few times).
Most of the parts are original but not all. A tree branch fell against the right front fender and hood leaving a minor dent. It has some small spots of rust on some body panels. The interior headliner is missing. The seats were re-upholstered. It has two installed gas tanks, the original and an extra added tank under the back of the car. It comes with extra pieces including a used 4-speed transmission which my dad intended to rebuild and install but never did. It comes with a broken power-take-off winch which had been installed but a piece broke and required welding, I don't know if the winch is complete or repairable. It comes with the spare wheel/tire. It comes with the original factory repair manuals and owners manual and also a Chilton repair manual. I have other small miscellaneous parts which will be included.
Buyer will need to pick up the vehicle or provide for the shipping of the vehicle at buyers expense.It is not currently driveable so will need to be trailered.I can be available to help load it on a trailer.
I have the clean California title. Full payment required before signing title over. I need to keep the license plates to return to the DMV.
