fortunately , I went to my local coatings/electroplater expert and he had a solution. He dipped the discs & removed the coating then replicated the wash Wilwood had used on the front. Here's a pic of one installed & safety wired.

with the rear axle sorted my original plan was to go with the leaf spring setup.
I ordered custom Hemi springs from Detroit-Eaton, lowered 2 inches (which when they arrived turned out as if they were raised 2 inches ). In the process I had to move the springs inboard 3 inches using the MP spring relocation kit.

..which included Caltracs at the front:

and THEN something happened...... I discovered THIS:

..and:

I say.. I gotta get me one of 'em..



So, I get on the phone to Unlawful Racing, and Daren irons and the great folks send me one. Turns out I am the first person to get the new product
Anyway, it turns up and it is an awesome system , with outstanding workmanship

so I get stuck into it. The springs, Caltracs, and QA1's on the rear I manage to sell. And we start undoing the spring relocation work... and fit the 4-link cradle into the car:

re-do the chassis rail (stronger), and the old spring perches:

then the rear brackets are (carefully) welded:

here's how it looks with everything mocked up (at first attempt):
