Got a local shop to swap rear supports for $20. It took him 5 minutes, off and on, money well spent. Tranny all but fell in place except for aligning torque converter holes. New tranny runs good, except it shifts hard into 2nd, but I'm using the original valve body and it shifted hard with the old tranny. Just playing around with the fine tunes. Adjusted bowden cable, fixed vac leak, vacuum to 14, tweeked VCV to 6 in HG at 10mm from stop. I'm going to run this car for a few hundred miles and change the filter again because of metal shavings. Flushed whole system clean, I hope. I will put another valve body in then to see if it shifts ok, if it doesn't I will Superior Kit it.
Paid $500 for 83 300d w/268k with a bad tranny. Had new tires, and one new trans axles, and brake lines. The A/C blows snow. Tranny cost me $86 from PAP. I'll have $900 in it before shes a cruiser. As always, the info on here was crucial.
