These are custom-made polished stainless steel brackets which replace the OEM brackets which usually have corroded up over time (or in many cases you probably bought a Z that has had its OEM bracket lost long ago.
Highly polished, the bracket set comes with fasteners and anodized machined cup washers (your choice of washer colors; blue/black/red/gold/silver) to match the theme of your engine bay.
They have been designed to sit slightly higher and room has been provided so that you may wrap your stock rubber block on the OEM cables with colored electrical tape (optional on your part) thus adding color to the Z cut-out in the bracket.
As pictured, a bracket set with your choice of washers are $35 shipped within the U.S. If you order more than one, additional brackets are $5 less as I can combine shipping. My Paypal address is: kmk@bricekarl.com, these are in stock and ready to ship!
