What @buggyman said. Always check the club store first. We like to support that if we can. Good quality products.
Just a question here, Have u checked to see what it takes to make your rig street legal there before you dump cabbage in it? U live in a Lib run state like I do and they have made it hell and ridiculously expensive to SL a sxs here.
I would bet you could adapt the 520 kit to a 500 pretty easily. Purchase 6 of the round indicator lights that they sell, mount them where you want them, and run the output to those instead of where they intended, which is the factory 520 harness.
Just a thought but you could E mail Grant at Turn pro and tell him what you need . he might be able to help you out he's a great guy to work with. [email protected]
