I've found someone who can build me a 700R4 transmission for a reasonable price. Unfortunately I have to pull the old transmission out myself. Not impossible, but its awful cold around here without heat in the garage. I suppose if I don't do it soon, I won't have it ready for summer. There's still lots of work to do before she goes to the paint booth, but the factory paint could last another year. I only get a couple of months of good weather to take the tops off, and I don't want to miss them.
