I had to grind off 2 bolts and 1 broke on the seat from my parts car. Is there a proper replacement bolt or do I just use something from the hardware store? I have 1 stud to hold it down for my cruise this weekend at least. 


Thanks for the tip, the bolts worked great!I have always used 5/16 carriage bolts with a retaining washer underneath the track to hold it in place putting it back in the car.
