Jeff, We have had a couple L's of your vintage come through our shop that we rebuilt. We did not replace the teflon bushings in the wippens, but did replace hammers and shanks. The case was refinished and restrung. We sold it for about $22,000. (At least that's what I heard, lowly technician I am) If it were up to me, I would have replaced the wippens too. I don't care for teflon and don't know many techs in the Boise area who will even bother with them. As long as you're hanging new hammers, restring it. We did an action rebuild on an M a couple months ago without restringing and although the new hammers made a difference, in the end we had to put on new bass strings.
