I'm installing New Glass and seals in a 48 pickup door and I hate to admit I was a dumb ass but it might keep someone else from being a dumb ass... I put the regulator bracket and seal on the bottom of the door window and fought it for hours and finally realized I put the bracket on the wide side of the window...(Hope this makes sense) And it's 3/4 of an inch wider than the other way . so hopefully I can get it off without breaking the glass and correct it... just thought maybe I could save someone else from making the same mistake... it's easy to do.lol
