I need help finding a part -- a new door check for my 1970 911. According to the catalog, the part number is 911-531-037-00. Here's the catch, and where I'm having trouble: all the parts I’ve seen have a 1 ¾” bolt mount spacing (44mm). My car has a 1 5/8” spacing (~41mm).
It looks like this:

It does not look like this:

Thanks for any help.
