[6pack] caliper bolts

["james mc arthur" <jrmcarthur@verizon.net>]

Good day to all! Can anyone tell me why the bolts that mount the caliper to 
the vertical link cost almost $10 apiece from Moss? That is $39 and change 
for 4 bolts!What is so special about them? As far as I can see, they are 
7/16" Fine thread by 1 1/2" long. Please, someone shed some light on this 
for me. Thanks!.......Jim McArthur- CF17672U
