before I take it all to bits and then have to go to B&Q fot the bolts I'd like to get them before I start!
if the job is done with a couple of threads inside a mount then excessive wear could occur, especially as the mount is going to be solid, movement will occur no matter how solid
I don't think a semi will give the same results
^ what he said, a bolt is a bolt, as long as the length and thread are right
