Pete 379 door frame

i have had to do this with shakers and volvo's
the volvo--like the guy said--if the whoole top is kinda out---make sure you roll down the window--grab door at top and heave ho
the shakers seem to be more of a door droop at the rear bottom corner
make sure your hinge isnt worn out--adjust it as close as you can to even gap---then under the rear corner of the door--a good 2by 4 from truck floor and out --and then heave ho then adjust with hinge and striker as you need


or get a kenworth

 

This has also been a problem on 359's for years, I've always thought it was the weight of the mirrors shacking up and down. If what I said is true then it should disappear on the newer model Pete's with the mirrors moved forward and off the doors, anyway Kroosers method is what most all of us old guys have done. Good luck
