Since owning the Elco the driver side seat has always leaned back further then the passengers. Really didn’t bother me much until wifey sat on it and is sitting way ahead of me and it blocks part of my view to the right window.
I checked out the usual possibilities and it turns out it is a cracked frame. I just went through this with my 2000 Chevy 3500 dually.
I ordered a hog ring plier and a bunch of hog rings. I plan on removing the driver seat cover and determine what type of work will be needed for seat repair.
