Hi , could somebody share the source for the 5mm spacer washers ( hardened ?? )used to space in the 911 "M " vented rotor rear calipers used by some guys in a 5 lug conversion on the rear trailing arms of the 914 . The 5mm spec seems to be the popular dimension to space the caliper inwards to center the caliper over the rotors , 20mm vented . Any direction to aquire these jewels would be appreciated.
Thanks .....
