Hi John,
Personally NGK would be my choice and look for 7 heat for that engine - the 5's that I fitted shortly after the rebuild if they are still in it were all I could get hold of and will run too hot.
Burton Powerignition and electrical / spark plugs / Pinto / NGKAP7FS
What Webers did you get hold of ?
I have found a few bits and bobs for the car as well
A clutch arm protection boot and tension spring, engine lifting eyes and dont now if I said before but I have a section of S4 bonnet to repair the hole where the filter is should sidedrafts be fitted.
Did you get the mail with the link to the fuse boxes etc.?
Cheers
Andrew
