That, if I remember was a hard find for me also...... I found a guy that rebuilds rearends and he sold me 2. Try looking up local guys who rebuild rearends. My bet is they with have a coffee can full of brake parts.
well, old thread..... Jim was and is a hugh help but a member here sent me 4 original bolts so I didnt have to order any. I'm sure they would work great if Jim is using them, just check out some of his restored KH brakes.
I think if you paint it cast iron gray it will stay cast iron gray. (I think they sell cast iron gray high temp) That's what i would do if I was painting mine.....
