alternator interchange???

Next time your square-back alternator fails, look for the diodes thru the rear window. The inner ones that "hang in the air" on the long bar would vaporize on my 82 Aries every 1-2 years, almost like clockwork. I got smart and started buying just the diodes and learned to take the alternator apart underneath the AC compressor so I didn't have to pull it off. By cutting slots in that bar with a bandsaw, I got them to last 3 years (better cooling). I haven't heard of them failing on Darts, so maybe the transverse orientation was the problem. I put a squareback in my 65 Dart, so I will soon gain personal experience.
