Pardon me if this has been posted before. I searched and found nothing.
My friend and I went out to the junkyard this weekend looking for 626 parts (we have 626's). We came upon some MX-6's and after noticing the 5th gen 626 door handles looked just like the MX-6 door handles we tried swapping them.
1998-2002 626 on the left vs. 1993-1997 MX-6 door handles on the right. The only trim the silver was available on is the V6 LX.
Here we compare the mounting hardware. The 626 door handle is taken from a front door handle but all you have to do is swap the tab from your MX-6 onto it and it's a perfect match.
With that said we then noticed that the backseat 626 handles are an EXACT match including the same mounting hardware. Here's a pic of the 626 handles in the MX-6 mounting hardware.
Oh and just in case you were ever curious about the 626 fog lights no they will not work. They are very close but will not work.
