My best of wishes to your parents.Great job and congrats on the MX-3 seats! Wish I could find/afford some. If anyone is curious my wagon-no start problem is posted over on the 3rd gen. section.
Have not posted here in quite a while due to poor health of elderly parents.
Try car-parts.com i used that site and searched for the seats. Got them for 100 with the double door center consoler and paid another 250 in shipping.
