I seem to come across some real loser project cars that I cannot resist.
Since 2007, I have fixed up and sold several A body cars. The CA cars are less likely to have rust so they are a good starting point. I used to have great luck finding little parts at the local self serve yards but these A body cars have really thinned out! The Pick N Pull yards have an online inventory to check but it isn't always accurate. You have to be there early every day to be first on the scene. A 73-76 Disc or 8.25 axle car gets stripped out real quick. It is to the point where you have to buy whole cars now to get a few needed parts.
I've replaced fenders, doors, quarter panels, etc. Most of these projects are only profitable because I do almost all of the work myself using good, used stuff. I built a small stockpile of sheet metal when stuff was easier to find.
I've had great luck with used engines, transmissions, etc. Almost every car had a thrashed interior. Only one car I sold had an interior good enough to leave alone.
My current project is a 73 Dart Sport 340 in TX9 black. The car came to me with no engine or trans. The K member was modified to fit a 440. I slipped in a low mile 360 but recently found a '73 340 that would be date code correct. I'm tempted to use the 340 but this 360 runs so well!
The car is the last of the 340 models. Cast crank, lowered compression but still a potent car for its time. Disc brakes, Black on black, 14" rallye wheels. I'm hoping to have it finished to sell in a couple of months.
