thanks guys! sorry for the misplaced circle. technically I'm looking for the door check itself.
so amazon reviews of the cheap ones include a lot of "had to mod to get it to fit" and "broke within a year". the mopar ones on quadratec are 100 a pop. ouch.

I guess I should go with the middle with a Crown?

this isn't something that's shared with XJ rear doors, is it? I haven't been checking them in the 'yards.
