I had Liberty faceplate 2nd, 3rd, and 4th. It was about $80/per gear, but you'll also need new sliders ($125/ea?). They have a new slider/fork setup that allows 1st gear to stay as a synchro. I took the whole trans apart and just shipped what they needed.

My order was over $600.00 but I had them do alot more stuff like rebuild the side cover, cryogentically(sp?) treat all the internals, etc. Call and talk with them, nice folks. May take awhile, mine was 8 week turn around.

In the pic, the old syncro sliders are in the bottom right for comparison.
