These are the things I am probably going to be making myself for mine:
Alloy T bolts for FHC B post grilles.
Alloy heater knobs. (you can get plastic)
Spun stainless alloy wheel centres
Stainless plates for rear of head lamp fixings.
Adapting alloy funnel to fit aero type fuel filler with pipe similar to original. (not really needed, but directs petrol into tank and not onto joint of tank/pipe, doesn't include breather pipe.)
Alloy Carb mounts using Weber type o rings and anodised black.
