If you're restoring your own calipers or having your calipers restored by us, it's a great (read: safe) idea to have new mounting bolts and wave washers. Talk about cheap insurance... you're not putting rusty old fasteners on your ride.
Each kit contains (2) fasteners and (2) wave washers. Each mounting kit supports one caliper.
***You'll want one mounting kit for each caliper***
Torque Spec is listed at 52ft. lbs. for the M12 fasteners and 34ft. lbs. for the smaller rear M10 fasteners on the early 356 and SWB cars.
