Opinion, you want opinion?
I am building my 48 at an old hot rod. And I am soooooo looking forward to driving a car WITHOUT powersteering, powerwindows, automatic, powerwindows,A/C, and on and on. There is NO WAY I would run a one piece or the butted glass. THAT, along with the cowl vent, the swinging door handles and what not is what MAKES the truck. Without all that old stuff, what do you have?
