I have been in hell trying to find this part since my seat track frame broke. I searched ebay with no luck since the main seller there mopargtx who sells some great Mark VIII parts cannot seem to keep the driver's side seat track in stock. The passenger tracks he has, but not the drivers. I called a few local dealers and they will try to rape you from $800 to $1000. Here's the actual part number f7ly6361705aa . Do a google search for discounted Ford or Lincoln parts. Even do a collision parts search. I was lucky to get a brand new seat track for the driver's side (that is part number above) for $650 including shipping.

I'm facing the same thing with my '98 LSC. Where did you find the one for $650?

yeah where did you find the one for $650? Ive tried everywhere including tons of salvage yards... just a pain in the ass! Would any aftermarket seats be a good fit?
