GMALT, a GM alternator kit for your XJ.

The kit is built to JCI standard specifications: 100% bolt-in, heavy duty parts (the adaptor bracket is 1/4" steel), all needed hardware, plug-in wiring (no splices plus it maintains the original color codes so your mechanic’s purist nose won’t suffer a fatal attack) and instructions of course. No cutting, welding, dents, drilling, or other modifications are needed. Black zinc plated so you don't have to paint it.  Add 10 minutes (to read the instructions) to the normal R&R time and change for the better to the best!

Kit does not include the alternator, what you’ll need is listed in the table below. For 68 to 87 6-cyl XJ Sedans, I recommend a GM 78 Amp unit.  If your kitty has a TV, FAX machine and Boom Box, you can still be happy with a heavy duty 94 Amps unit. V12 cars require more juice, so 94 Amps is recommended. Contact your local parts emporium and ask for the part number on the list. Remember you’ll need a new excuse to be late now – I am sure the cat will think of something.
