oh boy! my honest feeling about the opp door window kit: horrible design when used with the power window regulators. they def. need more R&D. i cannot believe they havent improved or modified their kits or atleast have 2 different kits-one with power and the other with manual windows. you have to grind the hell outta the inside front part of the door so all the factory bracing for the hinges is worthless. i ended up spending (not even kidding here) over 80 hours adjusting, grinding, opening up holes, drilling, and modifying their kit til i gave up and took her down to a well known glass shop that does hotrods for northern california named kidwells glass. the owner Dan said its without a doubt the worst kit hes ever had to install. he basicly had to re-do the entire kit and make his own brackets that adjust as the windows rolled up and down. he had the truck for 2 weeks!!! because he would have to walk away out of frustration! $500 later they are installed and work perfectly now. no air leak noise or anything negitive to report. if i had to do it again id drive the 13 or so hours without windows to southern cali and have Ben at one piece do the install himself.
