I'm in a bit of a pickle here. I am currently having my Camaro's 12-bolt rear rebuilt and I forgot to source the original bolts, nuts & split lock washers
that secure the brake backing plates to the axle tubes. All but one snapped while being removed. One that I saved appears to be a grade 5 "TR"
head marking fine thread bolt. There are eight ( bolt, lock washer & nut ) sets total required; four for each side.
Where can I get these on an immediate basis? Originality counts for me here, so I want the right parts.
Has anyone else gone through this ? Image shows only surviving bolt and correct washer/nut.
