Does anyone know where you can get the "highest" grade bolts now that I know size/length? I don't mind paying a premium for the best grade bolts out there. Sounds like the HD/Lowes option might not be high enough grade.

Stock bolts are grade 10.9 (It should be stamped on the head of the bolt). Metric hardware typically comes in 8.8, 10.9, or 12.9 for steel bolts.
RealOEM.com has all the vehicle parts diagrams. The stock bolt is p/n 07149321690 which is listed as M10 x 28mm long. If you're adding an inch of spacer (25.4mm) you can probably get away with 50mm bolts since some of the thread is usually sticking past the end of the nut but you could use 55mm long bolts to be safe.
McMaster.com has all kinds of hardware and a pretty easy interface to drill down to exactly the size and strength of bolt you need. For a socket head cap screw, they only have 12.9 grade bolt in 55mm long. You might also want a washer to replicate the flanged head of the stock bolt.
