Hi Nick,
The price so far is good, but the only things I would use from that car, are the engine and the wheels. The wheels can be cleaned up and they look great on an Alpine. The engine already has the early timing cover and a rear sump pan. The only part you´d still need, is an oil filter adapter from a Ranger.
I don´t ever believe anyone when they say that the engine has been rebuilt already. I would consider the engine a core, unless you can get it to run and can inspect it. A friend of mine, just recently, was sold an engine as rebuilt, and it turned out to have a spun rod bearing, and showd signs of abuse. The dirty condition of the engine, tells me that this engine has a lot more than 12K on it.
What I´m trying to say, is, don´t pay a lot of money for the engine, because it may not be as advertised. I´m also a bit suspicious of the missing carburetor. Seem a little bit convenient, so that the engine can´t be fired for inspection of condition.

P.S. I would also keep the electronic brain box and the long pigtails that connects the boix to the distributor and cut the pigtail that connects to the box, from the body wire harness.
