I recently started looking into this very thing for my 1985 'Saleen-006' (for those that get the joke) and found it was much harder than it was 'back in the day' - PRE SN95 swap parts bin era. These factors, over time, are slowly making it harder to achieve reasonable 60-0 performance on our old foxes for the crowd that love their old-school 4 lug rims. Now that 5 lug swaps are getting more and more popular, fewer cars are rolling on 4-lug wheels and real resources and info that is current in 2018 is getting a bit more scarce. I don't think I've seen anyone do that type of thread. You want it to look factory but drive much better than it did originally. So you're staying old school, eh? Traditional 4 lug, traditional coil springs, shocks, and struts.
