A good web site for PCD checking and some other stuff !
Automotive resources from carlsalter.com, Wheel rim PCDs and fitments, Free Motorcycle Service and Workshop Manuals for Download
There is also a BMW wheel at 120 mm PCD and looks similar to 411 S6 ! ( same as Bristol 410 to Blenheim and XJ Jag )
The 410 wheel is narrower than the 411 onwards -- although the 411 S1 maybe the same ?
I have new wheel nuts and studs for Bristol's -- only other car I found that uses same size is Land Rover S1 !! And no, they don't fit a Bristol :-)
I once fitted my Merc 112 PCD wheels to a 401 -- you needed arms like my wife's to steer it !! :-))
