Hi Jim,
Unfortunately, there is nothing off the shelf for the hardware. Dave at SSC has hardware in stock; if you scrounge the local scrap yards, some of the pop-out windows in vans and SUV's use the same basic mounting bolts (through the glass). You'll need to find a set that actually has the plastic or rubber bung that fits into the hole, though - that provides the barrier between the bolt and the glass and you'll avoid any unwarranted shattering. Is it just the bolts you're looking for or the entire hardware/hinge setup? SSC carries those, too (http://www.shop.sterlingsportscars.com/Rubber-trim-hinges-hardware-and-other-prarts_c9.htm), and search through Warren's posts about his Cimbria hinge setup.
