Pro Touring 4 link setup

[454SSguy]

Okay, so I've got a few things I'm starting to get a handle on now. I think I understand the RRC. I don't need to worry about calculating it really b/c of the watts link with a chassis mounted pivot. I can just put the RRC anywhere I want correct.

On to the new questions. FRC- from some very basic ideas I've come to the conclusiong that the FRC is lower than the ground. This seems standard on truck applications. I came to this conclusing because of the upward slope (from outside - inside) of the upper control arms puts the Front IC of each side outside the tires. This automatically puts the RC below ground. Please chime in if any of this doesn't sound right.

So control arms are the wrong way, like on older chevelle or other muscle car. What's to stop me from using a set of adjustable control arms and just make a new mount on the frame side whereever I want. It seems like a nice cheap fix to my problem. Build a couple of mounts to hold bushings for the upper arm and set it with the FRC where ever I determine I'd like it (~4" above the ground). I know that it's very rare that a simple solution presents itself so someone please let me know where my thought process is skewed. Other wise I could end up with a truck that could.....turn.
Thanks for the help in advance.
