I had a Mercury Topaz (basically the same car) that had the exact
same problem. I when to the auto wrecker and I didn't like any of the
front driver's seats they had. These seats have a tendency to lean
back too far and for a guy like me that really bugs my shoulders.
So, what could I do?
The solution was easy and simple. I took a a passenger seat and
bolted it into the driver's side. It was firm, upright and worked great.
The only draw back was the adjuster was on the parking brake side .
However, the adjuster was very easy to use despite where it was.
I have also wondered what seats from other fords would work. I think
you would have to look at what other cars shared the same part
number/numbers for for seat rails etc.
