I don’t remember 100% but I think I used 63Longtops brackets to mount my Wilwoods in front. Same front brake set-up Tom S runs on his street car. No problems. It went together very easy. You just machine the hub a hair and add longer wheel studs and it goes right together.
I rebuilt my entire front suspension with Kanter parts and the had it converted to a mustang rack (78-93 iirc).
The board member that bought my car ended up upgrading tp and entirely custom built k-member with tubular arms and a new rack set-up. It looks like it turned out really nice. I saw video of it running mid 10’s at Norwalk this year.
Edit: I think the shop that did the updates is in PA so you may be in luck. Also, who knows, he may still have my old front suspension set-up for sale. It was all brand new and fully powder coated.

I documented a lot on here as I built my car for reference for others. If you search some of my threads you’ll find good info from me and other board members as well.
