'66 Mustang kit questions

[ScottsGT]

Just a few minutes ago I stumbled across a photo of one of your mini Sub frame kits on the Vintage Mustang Forums. I have to have this set up! But I have a few questions first. Which spindles are used? Stock? Or any of the upgrades guys are doing on the Mustangs such as Granada or Versailles? Which springs? Stock style? Cannot seem to find much tech info on your website for Mustangs. Well, none actually.

OK, just found the install pdf. It appears as if the stock ball joint is used on the upper, but what kind of lower ball joint is used? I see the spring perch also needs to be installed and it looks like a stock springs set up from there. Really nice system!
I'll be ordering soon!
