I used ingot silver I believe and just rattle canned it the first time. Also used a standard aluminum silver a second time after damaging it that was pretty close.
I had not verified the brackets. I just re-coated the reps I bought and sourced new hardware. Looks like @w001475 got all OEM hardware though, so maybe he can chime in.
Not 100% on the tremor one, but for raptors it is HL3Z-6G079-C. If you look at the tremor diagrams, its under the splash and heat shields you'll find the diagram that shows #6g079, but I don't have the full number. I imagine it's the same part, but the # is probably different.
Everything, except what I noted was not required in parenthesis. Now granted you don't have to buy packs of hardware(could get individually), but it was cheaper to buy the packs for me.
One thing to note, the eBay raptor brackets I purchased are starting to rust. I would not recommend using...
