I have a line on a whole pick-up bed ful of 4500s, 5600s and G-56s from a yard that had sent their cores to a shop to build, then the shop went under.
Been trying to get an answer out of them on the whole mess for 8 months now.
Meanwhile it just gets rustier. :bang
Otherwise, I do have a 1998 2wd transmission with no bell or shifter stick parts, for $450.
Mark.
