Handle Bar Clamp/Riser Bolts

The bolt head stamping on the 2 stock bolts I've removed from the bike read 8.8 and that property class corresponds to medium carbon steel. They are also magnetic so definitely carbon steel and not stainless. I'll try a couple of local places first but a couple of M8x75 8.8 Socket Cap bolts should not be that hard to find from a reputable online outlet.
@2023R3GT could you provide a link for engineering works?

I will be installing the Voigt 25mm risers and have the TRIK GPS mount plate with spacers installed right now. The 55mm bolts that came with the risers are fine for the rear but I need 2x M8x75 bolts for the front 2 holes where the plate is.
Stock bolts: 30mm
TRIK bolts: 50mm
Voigt bolts: 55mm
I don't want to order them from the Bezos shop because I don't want to wind up with pot metal disguised as stainless (I believe that's what they are?) so could anyone here in the US recommend a reliable online source that ships from the US where I don't have to buy bulk?
