I didn't have to grind any of the the seats to fit them. You wringle the seat has threading the bolts in by hand to get them started. Get all the bolts started. Than you'll be fine. I got all of mine in with no issues.
Bump. Everything still available. Also have a pair of dark currant pearl driver and pass mirrors off a 99 accord, and a pair of 01-02 tan leather coupe headrests available. Mint condition.
