I saw a 70 e body with a later pad. Car had ac and now doesn’t have the vents either. Any problem swapping back to a 70 pad if lower frame was changed to a later year as well? Any difference in an AC lower frame and a non AC? Can you swap a pad without taking dash completely out? Seems the b body requires the windshield to come out to get dash out. What about these cars?
E body dash frames are all the same 70-74 regardless of AC or not, rallye instrument or standard cluster, you can change out the pad in the car, tedious job, it sounds like more work but it's actually easier to pull the whole dash and bench it, to pull the whole dash, remove the A pillar trim, 2 screws in each windshield vent, 1 bolt inside each kick panel, drop the column, undo the speedo head/cable, wire harness/bulkhead, vent/heat cables, then pull, no need to remove windshield that's a 2nd gen B body deal
