Hillerange Seaward Princess Hinge Repair

I have a two burner Hillerange / Seaward Princess range (#2172). One of the hinges has been loose since we got her. If you want to use the oven you have to tug the door upward slightly when you close it to get a good seal.

It "feels" like a loose mounting bolt, but my concern is the pivot hole in the spring arm assembly may be rounded out from use.

The good news is I've gotten far enough into my "to-do" list that I can deal with "annoying little things". The bad news is I'm not sure I can still get parts for this range and it looks like I'm going to have to remove it completely and do a lot of disassembly to get to the hinge (which is why I've been living with it).

Before I dive in I was wondering if anyone here has done this repair and if there's any info you can share?

Thanks in advance,
Jim
