seat bolts

wanna mount my seats this weekend.
are the bolts/nuts on the car reusable or are they welded to the seat?

Is the last what size/length do I need? (to mount the subframe to the floor)

If your taking standard seats out. All the bolts from them are welded to the subframe which is attached to the seat.

You'll need new bolts to bolt a new subframe to the car. I just went to my local hardware store. Can't remember the size exactly but its a very big hole. I just guessed a size closest the the standard bolts I could find. Cost me like £2 for a set of 8 chunky bolts including washers and nuts.

Even if the bolts are not big enough to perfectly fit the holes in the frame or the chassis you can just use a chunky washer.

You should use high tensile steel bolts. 12.9 is preferred IIRC.
