where can I find the plastic surrounds for mini humbuckers (black, white, cream etc.). I am building a custom rear routed stratocaster using warmoth parts and I want to install SD minihumbuckers. I need the surrounds for a clean look without using a pickguard (I don't want a pickguard to cover the beautiful woodgrain). I do not see them at Warmoth, Seymour or Stewart/MacDonald. Can anybody give me a website for these?
