You could do me an enormous favor by measuring/photographing them as well. An useful overview of differences between the CB500, CB500K1 and CB500K2 (ED, F, G) which was different from the CB500K2 in the USA is found here (scroll down) www.honda4fun.com/home/faq/generali/111-cb500-differenze-k0-k1-k2 Then you'll understand the lugs. The CB500K2 (ED, F, G) was marketed in Europe in 1976-7 and shares many parts with the CB550K2 '76. The CB500K2 (A) was marketed in 1973 in the US.

Sorry, as I said, I traded those with James but I am sure he will measure them for you if he's not used them yet. The photo I posted was an internet shot, not the traded ones.

I'm studying your pictures and I wonder if the metal where the holes are (those for mounting I mean, so one top and two down) is supposed to be parallel. Would be nice if anyone with a stock, undamaged set of brackets had connections in the 3D-printing world, btw.

I've spoken with the Netherlands this morning. I've been assured that it is normal for some exhaust gas to leak from the muffler studs, and that it will clog up quickly to create a seal. If it doesn't work after a hours use, then I should contact again to discuss further options.
I'll keep you posted. Think I might give it another go this weekend, using Ash's measurements from stock brackets.

The exhausts seemed to be level when I fitted them, just not in line vertically. I'll double check this weekend.

I hope Ash is accurate. I'm measuring myself right now. The top brackets (18435-374-670 and 18345-374-670) seem pretty close. I suppose when measuring the height as in Ash's pics my top brackets I have to ignore the lugs that are welded on. The lower brackets (18430-323-040 and 18340-323-040) are of but I haven't figured out which way is best to rebend them.
