BROTHERS one-piece window kits eliminate your Chevrolet or GMC Pickups vent windows and give your truck the smooth appearance and smooth operation of one-piece glass. This special cut of glass on our 55-59 conversion allows for complete sealing around the window and easy roll-up or down operation. Our glass kit was painstakingly designed for easy installation and use. The glass is available in clear or tinted (check local and state laws regarding side window tint). Dave Welch is a classic truck Specialist and he’s got plenty of tricks for nearly every project on your classic.
