I've had my 1957 Oldsmobile Super 88 2 door hardtop for awhile and it has always had a cracked passenger door glass. I final bought a replacement glass from Autocityglass. I've not had a chance to install it yet but it does look like it would fit, based on sitting it next to the old glass. The glass replacement piece is narrower at the front and wider at the back which seems to follow the lines of the door. My question is, is the glass channel angled also inside the door to hold this angled piece? I'm not sure how soon I can get to replacing this and I don't want to wait too long in case it is not the correct piece. Thanks.

 

No. it's not angled. 90* with the outer window channel.

 

I pulled the top metal door trim piece. The glass is indeed different lengths from front too back. The front glass measures about an inch shorter than the rear. So, it looks like the replacement door glass piece is an exact match and should work.
