alternator fit perfect
after simple install of alternator fired right up charged great super bright headlights think this is the only production option for the alternator with belt tension was worried not look original but black alternator is great

great product
Three washers on each side of the alternator, along with the provided spacers, took care of a small misalignment. The misalignment was about 1/4”. That was the only issue I had with the kit. The alternator provided significantly more power than the original generator. On a 30 minute test drive, when you called, everything that could be on was ( lights, heater and defroster fans) and it provided plenty of power on highway and stop and go traffic. Just a slight discharge was observed stopped in traffic with the brake lights added to the above load. It performs as I had hoped and we’ll put some miles on it over the next few weeks. Thank you very much for your calls and support during the installation.

great to have companies that do these kits
I started on the Caddy today. I've installed the alternator, starter solenoid ( I had to elongate the mounting holes, no problem) and the coil. So far, so good. I'm going to start on wiring next. I'm glad there are companies like yours that help make these old cars more drivable and dependable.
