Might end up having to do that and grabbing some thread locker just to get the car driveable. A lot of people seem pretty adamant that these bolts should come from the dealer, but I guess 10.9 is 10.9 regardless of where it comes from?
I stole this info from another thread, just posting it here for reference since I've subbed to this one.
For the REAR -
GM Part Number: 10229606 (Rear caliper bracket bolt) - (not a good number anymore)
Description: Metric Heavy Hex Flange Screw
Measurement: M12 X 28 X 1.75
A lot of these online parts places seem to be the same central place with 100 different storefronts, but I've tried another just to see what happens. $22 shipped for four is worth the time saved, esp since fastenal and the like would sodomize me on a single bolt anyway.

Good info to have handy.

They are. On the front end, they are the same software/web company and catalog functionality. On the back end, they have different price lists and are affiliated with different independent dealers across the country.

They don't do this often, but they do substitute new part numbers. (There are a number of reasons why they do this.) Just go to a local dealer. They should be able to look it up and get you the most current story. They may even have them on their shelf.

I've never seen 10.9 bolts at these places. Only specialty/industrial supplies.

I have to admit, Menards has a great selection (at the least the monster store in Schererville IN), but makes it difficult to actually find their 10.9 bolts. I'm impatient, so I've skipped past them lately. Tractor Supply has been where I've had the best luck -- 100% "find" rate for all the goofy bolts I've looked for recently.

I bought 4 of these last night at Lowes for putting ls1 front brakes on my chevelle. M12x1.75 thread and the ones I bought were like 25mm long but they had longer ones you could trim down if that's too short. They are just in the metric bolt drawers, but they are 10.9 grade according to the tag and packaging. $.92 each

Cool. Online orders keep getting canceled so I'll swing by Lowe's in the morning to see what they have. Tractor supply was a thought but I don't know of one around here. Thanks for the help.

Whenever we need an off the wall size bolt we turn to McMaster-Carr. This is the closest size supplied earlier in the thread - Grade 10.9.

EDIT: followed the link and it didn't send me to the bolt I wanted. It's this part number: 98093A751

Cool, thanks. They have a location down in Atlanta so that's cool. I have to use a washer as a spacer anyway so a 30mm should work fine. $9 for ten bolts? Hard to beat that.
Just a random data point - ordered from McMaster at 10am and the bolts were at my door that night when I got home.
