I need to replace the little rubber bellows that cover the caliper slider pins on the front brakes of me '86 300E (Girling calipers).

The dealer wants $32 for the bellows and 8x20 bolt that holds the sliding part of the caliper on - for just one! I need four. Is there any source for these bellows that's a little more reasonable? BTW, it doesn't even come with the caliper rebuild kit.

Any help appreciated,

Thanks,

Gary
