I am the club member Bennett is talkign about. The tranny was like $310, and the shipping was about $75. $385 was HALF of what I was quoted to have my SM420 rebuilt.
I got a New Old Stock Gamma Goat transmission from a place out in california.
The tranny is essentially a NEW SM420, but with a few minor differences.
The tranny is nearly identical to a 1967 SM420 from a GM pickup but with a few exceptions.
First, the entire top cover is different. The Gamma Goat uses a wonky linkage shifter. This isn't a big deal if you already have a good top cover from a later SM420. It will swap right on.
Second, the 'passengers side' face of the transmission does not have the cut away that the civilian version has. It's a solid 3/4" thick plate. So if you are running a passengers side TO fork and bearing, you will need to grind a hole for the head of the clutch fork pivot bolt. This was a non issue with a 1/2" drill and 1/2" drill bit.
Third, the Stock H42 shifter DOES NOT WORK WITHOUT MODIFICATION. The end of the shifter that goes into the shift rails needs to be extended about 3/4 of an inch. Once it's extended, it will drop right in, engage the shift tower pins, and make things look liek they are supposed to be there.
They say ConDiesel all over them. I think they were found behind a continental or perkins diesel in the gamma goat.
Finally, I posted a thread over on pirate with pics of the tranny I received. When I got it it was sealed in a plastic bag that said General Motors on it, and it was wrapped in a Cosmoline soaked cheesecloth.

After installation, the tranny shifts just as smoothly as my H42 did. No noise. No problems. This thing has been rock solid since. It's done 3 moab trips, 1 maze trip, 1 san rafael trip, and is my daily driver. I have absolutly NO regrets from doing this swap other than just not buying the Gama Goat SM420 to begin with!
