LoL. Nice volley!
i think there is a misconception that the "Mustang II kits" are parts from, or built exactly like, a Mustang suspension. Truth is, they are not. The concept and the geometry of the Mustang II is what is used to fabrictate these kits, which are mighty beefy. Did a Mustang come with tubular control arms? Nope. 11" brakes? Nope. Want a sway bar? No problem, the kits do indeed come with a sway bar if you ask for it. The kits also come with pre-cut boxing plates, designed to fit the vehicle you'e working on, and the kit comes with the proper springs too for the vehicle. No fabbing required, no plasma cutter required, no fabrication required to allow the front sheetmetal to bolt up (that sounds like LOADS of fun!). Rack and pinion steering came on T'Birds too, much heavier cars. That's what comes in these kits ('88 T'bird units). And the kits come with new components, not 30-year old pieces with unknown history, potential damage (if it's coming out of a junkyard, why is there?). LoL. Unlike clips, that have 30+ years of wear and tear on them, that need to be (or should be) rebuilt, need to be inspected for damage, repaired as necessary, etc. 1/2-ton pckups aren't much heavier than Mustangs anyway. Getting the wheels cntered in the wheelwells is easy. Measure twice, weld once, that's all.
But to each his own, I was simply trying to offer another solution that may prove to be more cost effective, easier to install, and come with new components that were designed to work on the vehicle you're building. Sorry for being a jerk.
