I just finished final assembly on driver and passenger doors on my 50 truck model 3100. Both my driver side and passenger windows all work fine except both windows stop approximately 1" from rolling up all the way. My regulators are after market. I can't find any nut ,bolt ,etc. hanging them up. Is it possible my install of of both regulators not "clocked" correctly where 3 screws attach? Wrong regulators or just plain junk. Thanks in advance of any suggestions. Old Norse
