Sorry to ask a stupid question, but my block is at the machine shop for a spell, so I can't answer my own question. I want to replace my bell housing bolts with ARP and don't see any specifically listed for the Buick 455. The ARP Chevy ones are advertised at 1.375" and mine are all 1.25" Will these work? ...just want to make sure I don't have any bolt interference issues. Thanks!
