I would hate to go through all this trouble and put the tarnished hardware back on there but the size of the main bolt for the bracket that attaches to the frame is M8x1.25x16. Proboltt-USA.com only has M8x1.25x20. It's only a difference of 4mm in length but it's not the same (Captain Obvious). Also it's a hell of a lot cheaper for aluminum then titanium (again Captain Obvious) but would the aluminum bolts work just as well? One reason I ask is because I can get the aluminum bolts in anodized black which I like but don't want to compromise the integrity (safety) of the bike.
Disclaimer: Enertia+ rider, not Empulse, so I don't know *exactly* the lay of the land you've got before you. I will caution against mixing metal types in some applications, as it can easily lead to seizing. You can coat some bolts with grease or more appropriately anti-seize, depending on what they're made of, what they're going in to, and how much load bearing they carry and the torque that load would require.

you're dealing with cap head screws (aka "allen bolts") from the looks of the pix below. Here's a set, not cheap ($12 for 10) but not Ti-priced, either, and I even selected them in stainless, so if you wanted to polish the heads and make them all shiny they'd be good candidates:
