It's easy, most suppliers of splined hubs do:
short: 13" wheels
long: 14", 15" wheels.
That is normally stated on their web site / in their catalogue (as i'm sure there may be differences out there!) and i found that if you give people a quick ring they will normally confirm this with you.
There are a few suppliers around who all charge about the same and all supply similar (normally the same!) adapters. Some people have their preferences about supplier, but due to a mix up with my initial wire wheels i tried a few different adapters from a few supplies before i found out that i had the wrong wires (DOH!) and all the adapters i saw were identical quality.
Took the small scoop off the car added bigger one. Altered bonnet need more clearance bugger ! . Took off bigger scoop. Altering hand brake position need to weld. I advise make sure you can remove tank easily wasted 2 days.
My guess is it's strawberry flavoured spray cream - you round up all the stray cats in the area, liberally apply spray cream to the rough patches on your bonnet and the cats do the rest. Saves hours of sanding...
