Well, if you still have the stock bolts, chuck a soft to medium wire brush into a drill, put a stock bolt through an M8X1.25 nut, tighten the nut into a bench vise, and wire brush the bolt heads.
When all 4 bolts are done and looking bright and better than new, punch them through a piece of cardboard and spray the heads with a little SEM clear. Voila, perfect, pretty and better than factory.
If you're missing the bolts, I don't have my 44W book in front of me, but so far as I recall, they're M8X1.25, whatever length, with a washer style head. If you can't find something suitable in the stainless section of your local Lowe's or whatever, then try:

But trust me, the factory bolts done this way look awesome!!!!!!!!!!
