I don't expect a 48 Chevy truck to be like a new one but it has wind noise starting at 70mph that requires raised voices to communicate. Has one piece side windows, one piece windshield, Steele rubber, all new felt and window wipes, bear claw latches, door gaps exactly one paint stirring stick wide and door flush with body all around. Can't slam door closed without cracking a window open so its tight. Fire wall, trans cover, and even dimmer switch is sealed. Fire wall mount MC with gasket so no pedal holes. Accelerator cable has thin rubber seal to fire wall. Any suggestions or is this just a fact of life with a 71 year old truck?
