I realize that not many of us here are running the Mustang II front suspensions, but someone out there might have an application for these.
I purchased this kit brand new a couple of years ago for my father's 57 Ford project, but we never installed them. Actually, I have never even opened the boxes. It's the 6-piston Wilwood Superlite 6 calipers with 13" rotors (12.88" x 1.10"). It's the complete kit as supplied by Wilwood for the M-II application. You can see the details on Wilwood's site at:
Superlite 6R Big Brake Front Brake Kit
It's 2 rather heavy boxes. They are located in Austin, TX. New, they are about $1700 from Summit or Jegs. I'll do $1100 shipped to anyone here that wants them.
Additionally, I have a pair of 4-piston Billet Dynalite calipers, also brand new and still in the boxes. Same story, these were purchased to replace a pair on the 57 Ford project, but were not used. New, these are about $300 or so. I will sell the pair for $175 shipped.
