I can't answer your question unfortunately but i will comment that as an owner of a jag suspended cobra the components are extremely heavy for a car that weighs 2/3 of the the Jag. don't know your regulations but i would have new A arms made up of suitable tubing, keep the upright and have an Aluminium Hub made with Aluminium callipers - the reduction in un-sprung weight will be huge.
I have the Al. hub and Willwood calipers and the difference is very noticeable - the ride is noticeably harsher so I could use softer springs and damping up front for the same suspension frequency as the original.
