i'm looking for a set about 160mm long tip to tip with a thread on one end of M11 and i think it was a 1.25 pitch.

any one know what cars have something of that size?if longer it's not a problem

probably useless info but i know you can get arp stud kits for the vauxhall xe engine but no idea of the length/ you prob already know this as your location mentions a cavalier...

No help but ARP also do main bearing stud sets, might be worth a look if you can't find what you want in the head sets.
