I posted a wanted ad on here a year or more ago for just the left hose bracket and still have not found a seller willing to part with it. Hope you have better luck than I have.
I'm having a friend of mine fabricate something up for me.
I had a spare pair of them that i sold off two years ago, figuring i would never come across a pair of calipers to rebuild that would need them.
Boy was i wrong. Should of kept them. Oh well, live and learn. i guess.
I did get one response from someone over at bigblockdart.com but he must have thought they were made out of platinum, and gold, the price he wanted for them.
I'm sure my machine shop friend will make me something that will work quite well.
