Thanks for the comments guys
71Nova- yes I am building the entire frame. It is 2x4"x.120" wall tubing.
awr68 - Wheels are 12.5x18" CCW classics and the tires are 335/30/18 Michelin pilot sports. ( I REALLY wanted the BFG G-Force TAs but at the time there was no info on them and i needed tires to mockup with) For the rear suspension im building a 3 link and the front ill be building everything from scratch but using modified stock geometry. It will be bagged but also have all the mounts for coilovers so i can switch between the 2 depending on what i want to do.
907rs - no Truckarm anymore. After I learned the advantages of the 3 link and also the cost benefit I decided against it.
Here are some old pictures of the mid secton of the frame. It's not done yet but you can see how it sits in there.
