Kim, I'm not sure why you are confused about your wheels. If your broadcast sheet lists code 29 (which is the code for part number 2944329) then wouldn't that be the correct wheel? I think you have definitive proof. Eric is missing his broadcast sheet so we discussed the various reasons why different part numbers exist for the same part. It could have been a production date issue or maybe an assembly plant difference. Who knows for sure??? Regardless, both your broadcast and mine list 29 as the correct wheel. Your production date is May '71, mine is Dec. '70. The only difference is that yours were painted black and mine body color.
