Source for rebuilt transmission?

[Kerrigan]

After some talk I got the cost of the rebuild down to $700 cash. New bearing kit with syncros, gaskets, and seals; new 1/2 shift fork, new 5/R shift fork, 5th gear (used but not pitted) and the 1st gear and others from the donor transmission I had. Shop gave me a nice discount for cash :-)
I think they are pretty good rep wise, although it took a long time and many phone calls to get them to complete the work. The place was packed with cars having tranny work (new shop) and a nice race car was sitting outside waiting for work on it. 6 month 6k mile warranty.
The 5th gear in BOTH trannys had a lot of little pits which he said came from static electricity damage and weakened the gear making them prone to loose teeth. Said only use Pennzoil Syncromesh GL4 oil in them or the brass syncros would get eaten up.
Also interesting is he pointed out the differences between a couple of these transmissions of '79-80 vintage; they are not all the same. Like the bearing for the input shaft is different, one will not fit into the race of the other; different snap ring diameters, etc.
I thought they were all identical, but apparently there are different versions of the KM145. Showed me how ordering rebuild kits off the Internet can leave one with the wrong parts ...
