SSR Carbon Valve Cover Protectors.

[JMitchell]

I recently purchased a pair of SSR Racing Valve Cover Protectors. Beautifully crafted. I now realize the original bolts do not work and it requires purchasing a two piece type bolt. The picture below show a set of four for $25.00. BMW now charges $60.00 each for the stud. Does anyone have any experience with installing these cover or know where to purchase a set of 8 as shown as #5 and #6 in the picture.
