Didnt mark t-bars before removal :(

You need a shop manual. I don't mean a Chiltons, Motors, or Haynes. I mean a FACTORY shop manual. Since you have a '72, you are one lucky guy, 'cause AbodyJoe has one you can download for FREE

The bars should have a number stamped on the end. The odd number goes on the driver side, the even goes on the pass side. Leave the front nuts on the LCA lower pivots a little bit loose until you get it sitting on the ground.
