while i'm awiaiting the sale of my stuff....i still want to educate myslef incase i have to keep it and use it down the road. I have the 39 backing plates and they need all the hardward. Macs has all of it new...and I have scrounged up some used parts, but my question is about the brake shoe cam. where does it go in relation to the set up. any pictures would be helpful. I am also at a loss as what to do with the 2 adjusters on each side of the plate. they work and turn but are rusted and ugly. they are riveted in and i don't know how or where to replace those pieces. thanks.
