Hi all, forgive me if this is covered elsewhere, I did look .... honest.
I replaced split and crumbling exhaust bobbins on my Plus 4 and found the U bolts and flanges rusted. I have put them back for now and would like to source stainless steel replacements. A quick search online failed to reveal to me S/S equivalents and so here I am at the oracle looking for some guidance. They are 5/16 UNF U bolts (same as the bobbins), the flange marked 2 1/8". The replacement can be metric or indeed any other option as long as they fit and locate properly through the holes in the bobbin bracket.
All help welcome
