Replacing turn signal switch unit / bolts

[sevenbucks]

Hi everyone,
My bike's original owner never covered the thing and just left it out, so while it works (though should it sound like a lawnmower?), cosmetically, it looks like ass. There's a couple things I'd ultimately like to spiff up or replace for looks and more reliable function. Mainly the brake fluid tank which is battered, and the turn signal button. The switch sticks in all positions and rarely cancels properly, not to mention it's battered too. I'm wondering if any of you have taken yours apart and got them working, or can suggest a replacement?
Other question I have regards the rusty bolts and nuts I've got here and there on the bike. Are these all fairly standard parts that I could replace at a good hardware store, or is this a more specialized search? I've seen some of the posts here, but don't remember seeing anything about the hardware being easily obtained like at a local store.
I apologize if these questions sound basic; when it's slow at work I day dream about being one of those Biker Boyz and tricking up my GS to a spectacular level of tackiness.

I ran into a similiar issue with my GS when I picked it up.  The signals were rough...
Goto www.bikebandit.com and look up the schematics for the switchgear.  They are quite easy to replace and on my 92 the new switches make the bike look a lot better.  I replaced both sides as they originals were both sun faded.

I have been able to replace some of the bolts at a good hardware store with a metric section.

If you have a Suzuki dealer nearby, the OEM stuff isn't TOO expensive.

If not, you might try Bolt Depot.

I just did a total rebuild of a badly abused GS. The bolts are easy but they're metric so watch that.

Pay the buck and get stainless. As to other parts, a shop that does lots of bike ( damaged ) repair is a source for cheaper aftermarket, and DennisKirk.com is the Mecca for metric bikes. If they don't have it, good luck.
