Really couldn't stand the look of the dangling adjuster. Screw the old one out, transfer the spring, screw this one in and you're done. Also, you can still adjust the idle speed while sitting in the seat (on my 94 WG). Highly recommended.

Very nice piece. You do need to remove the switch housing on that side, drill out the existing hole and tap it. (Tap not included but a standard size). Works precisely as it should and a big improvement over the stock set up. Oh and it looks great too.

Solves the dangly speedometer cable effect of the stock idle screw, easily modified. I put a chrome dice on the end of mine and it looks trick.
