Well, I don't understand it. Just looked at the other 3 cars and they have the same pitch and the blades are on there the same way as the Duster is. I know the 69 Plymouth is factory correct because it has not been messed with. Took a sheet of paper and put it in front of the radiator on the Duster and it pulled really good. Not pushing air out the front this morning. It is sucking the paper tight against the radiator. Held my hand behind it above the water pump housing and there was a lot of air coming back. The thermostat is new . Maybe the water pump is going bad, so I just ordered a new Milodon high volume water pump to put on it because I don't think I have ever replaced this one since it was built. I also ordered a new 16" pusher fan just incase I needed it. Anyway, this should cover all the bases. Will let you know how it turns out.
