Billet Aluminum Wire Looms for sale
 

I bought these and worked great but now have new looms for new valve covers. They are made from billet aluminum and are made by Mr. Gasket. These will fit 87+ model centerbolt valve covers. Only problem is that one side has two tabs broke off when trying to take off wires (see pic). I used 8.8mm wires with a tight fit. They are made for 7-8mm wires. You should be able to get different colored tabs from Mr. Gasket to replace these to fit your color scheme. New they cost me $50. I'll sell for $30 plus shipping.

I will also be posting the black valve covers from the ZZ4 for sale as well soon. If interested I can ship together.
