seat bolt broke inside
 

i was taking out my seat couple months ago to get the carpet out, and the bolt was so rusted that it snapped right in the hole leaving none sticking out. How can i get this bolt out?

drill it out and re-tap the hole

yup CyniKal.Mindset is correct drill it and retap the hole
its the only way or you can weld the seats to the floor

dont weld your seat to the floor, ive tried and you have to be very careful of the carpet not getting burn and chances are it will get burned. the right way and i think the only way should drill and tap.

good luck on drilling out the other half (deep as hell)
