Hi, I haven’t started a build thread yet, so as an emergency option com gonna ask here. We are installing the front calipers and we couldn’t find the caliper bolts in the box with brakes (standard brakes). However from one of the previous steps we have exactly 4 bolts that fit calipers perfectly. I’m still confused with them though. Are these the bolts that we supposed to use for calipers?
Also we don't see any other bolts in the box with brakes stuff that would work here.

Those look like driveshaft to pinion flange bolts you me.

I also concluded that they were for the calipers
Wilwood ships the brakes with caliper mounting bolts, and FFR supplies a slightly shorter 35mm vs. the 40mm from Wilwood.

that's the thing, I didn't find any Wildwood-supplied bolts in the boxes.

The FFR supplied bolts are what you want to use anyway, so I'd say you're good to go.

I agree with Murd.
I think the drive shaft bolts are smaller than the caliper bolts. Also, the drive shaft bolts should have thread locker on them. They should be in the same box as the drive shaft.

It looks identical to my drive shaft to pinion flange bolts.
One sure fire way to ID the part is to compare it to your inventory.

If it has a 12 MM head it is a caliper bracket to spindle mount bolt, there should be four.
IF it has a 3/8 or 7/16 head it is a header bolt and there would be 16.
Driveshaft bolts if IRS are hex head bolts. If Three link they are 12MM head and have thread locker on them.
Looks like a caliper mount bolt to me.
