    Rated 5 out of 5 by from Nice Bracket I bought this a month ago to replace the cheesy one that came with the NOS kit. It's well made and looks better.

    Rated 5 out of 5 by from Works like it is supposed to Tapped the holes in the Holley 750 DP, installed the JEGS billet micro switch mount, adjusted the micro switch, it hit on the body of the throttle plate so I ground a little off the switch tab, wired up the solenoids and it worked perfectly. This is a very good quality part and much better than the flimsy switch mount that comes with most Nitrous kits.
