Ted, are the bolts (flanged) the same style on the 500/550 as the 400/4 ones? - ie reduced head? I'd like to source JIS (reduced head) flanged bolts but the only guy I have found so far wants around £12 a bolt!! - I could make them for much less. Let us know if you manage to source any 8mm bolts with 12mm flanged head in S/S...
I'm going with Middletons 8mm bolts for my crankcase Ted, I like to know they won't rust and look awful in a few years. I'll also zinc/nickel plate my old ones as well and make a decision if they look really good.
