I will be making some adapters so the Mx-3 front seats will sit level in the pre '90 323's. I'll take some pictures when I get mine done later this week. If anyone is interested just PM me and I'll figure out how to get some to you.

 

your rails from ur stockers didnt fit? or was that already tried

 

The rails from the stock seats fit, but it causes the MX-3 seats to lean toward the center of the car. Spacers and longer bolts solved the problem.
