Anyone use non mopar seats and rails?

I put 03 wrx seats in mine, actually sat in the car for the first time in 12 yrs last wk!!! I cut the factory mounting tabs off the seats, (below the sliding tracks) and welded flat tabs in their place. Then I used some box steel as mentioned. to get the correct depth/height to meet my factory bucket holes. I have seen company's sell "brackets" that will mount aftermarket seats in our cars, I dont know if they would bolt to your escort seats...
