Got a new/gullible/simply dumb friend/ coworker/relative/employee who talks a big game when it comes to automotive things but really doesn't know jack?

Send him out for a half-pound bottle of blinker fluid, a new johnson rod and a couple of adjustable powerbands from this site, styled to look like a real autoparts supply....

KalecoAuto.com. Many other essential parts and gizmos at the link, too. Worth a browse through.
