    Something like this would also work well.

    I've used it to insulate luggage from exhaust heat.

    I've had good luck getting individual stainless bolts from http://www.desmoparts.com/ High quality bolts, great selection too. He has kits for some bikes, but a separate page for individual sizes.

    In reading this, I had some thoughts since I've had to deal with metric hardware in a sideline project making cam chain tensioners. If you did some digging might find the 8 is a rounded M8-.075 fine thread pitch. They do two fine pitches, M8-1.00 and M8-.075 threads per millimeter. But I'm guessing. The coarse 8mm thread is M8-1.25 threads per mm.

    Here is a link to the ISO charts

    I buy bolts at Fastenal, where they can be ordered individually (if not in stock and usually not). Problem is washers and nuts are not sold in singles. Just pointing out the alternative. I am fortunate in having a really good old style hardware store for the goofy or single stuff. I use Fastenal for my quantity purchases though.

    Make sure you use anti-seize on them for sure when steel on stainless or stainless on stainless. I am not sure about aluminum. Seems when the bolts/nuts are threaded together the scraping of the surfaces causes some removal of a material that surfaces to avoid corrosion, then the material will bond together - aka sieze up. My brother used stainless for a nut/bolt pinch clamp on a Betor fork axle clamp. They seized and he had to snap the bolts to get them off.

    I'd certainly check on the aluminum/stainless reaction to be sure. Here's Fastenal's take on it.

    Here's another expert's take from an expert in the industry based on what I've found on a net search, Joe Greenslade.

    Giant skid plate has a 'tool box' on each side.

    I run 87 mostly, every so often I splurge and put in 93. It runs exactly the same.

    Yes but then you would have to cut and match the complex curve angles of the tank area around the fuel pump intake. So much easier to reorder the tank heat shield that comes on the OEM tank and place that around the fuel pump. That is what I did; it fits quite nicely and it took about 5 minutes with the tank off prior to its first installation.:D

    Anyone else's license plate light really loose? I tried tightening the bolts but there is an internal spacer that prohibits making it any tighter plus the nuts are capped. Is it loose by design? Shorter bolts or a standard nut makes no difference due to the spacer.
