The LC2 uses a CS-144 running at 120 amps. There are several CS-144 configurations out there. The differences can best be summed up as differnt clocking (how the front and back half of the cases are aligned), amp (I want to say I only came across 2 variants, the 120 and one lower, can not remember what it was), and pully (differnt diameter, differnt fan). I am also certain there is variation in the regulator but that did not matter to me at the time, I was going to replace it anyway. As for the amp rating, I found that often it was stamped on the front of one of the mounting ears. That can be wrong, however, if it was a reman. The amp is decided by the stator, that thing that you see from the outside sandwiched between the case halves. If the reman shop does not keep the 120amp stators mated with 120 amp stamped cases then, well you know. As to finding them, its ease. Look for mid/late 80's V6 intermediate sized cars. Mid sized caddy's, Rivera, Pontiac Bonny, etc. Something that would need some juice to power electric toys. The case is easy to recognise, the 144 was a beast of its own. In my situation I wanted to keep the origional case. I have a TTA. Even though it also uses the CS-144 the TTA has a rather difficult to find PN stamped in to the case. I wanted to keep my factory part so I found a replacement that I could modify, smooth, and powder coat. I went a little farther in that I dug up another 120 amp unit with the same pully so that I could leave my factory part together (IE I did not have to steal the stator and pully). In the end I decided that since I had it apart I would up the juice. I ended up with a do it yourself kit from trubobuicks.com.

They provide a 200amp stator, new brushes, a rear bearing, and a regulator. I figured for the cost of the kit I was just a little over what a clean and test of the used stator plus replacement parts (brushes, regulator, bearings) were going to cost me. I ended up just picking up a front bearing to augment the kit. The rebuild is real easy, there are directions in the Tech section of gnttype.org.
