I have a $875 Cali. Performance (orginal Art Carr) Torque Converter for $600 shipped. Less than 3000 miles on it. Switching to powerglide.
Shoot me a e-mail if your interested.
My buddy has a 9.5" 3500 Non/lockup for I believe $300. It's probably got less than 800 miles on it. It's in his HotAir that lost a rod and he's bought an 87 and doesn't need the convertor any more. Call him at (270)-303-7281 ask for Marty.
