I have been using Revit Architecture 2012 to model a few things on the Blazer. I also acquired some parts over the last few months and have done crap loads of research and parts watching. I have studied the chassis, firewall, steering box mount and all the parts that I know will be going in and it plainly came down to making a serious decision. I was overwhelmed with the thought of cutting the frame at the firewall, effectively removing the strongest section of frame and leaving the weakest in tact. So I took several measurements across the body and frame - most important, the body mounts. I chose the wheel and tire size I would like and modeled them to scale (or close anyway). I then started modeling the parts I had in hand to use or reuse.....



This where I am at right now - the rear floor section has been modeled, the fuel tank with connections at the top, the body mounts, the Cage Offroad radius arms, reference points on the frame and body.


I aim to build a tube chassis or perhaps a hybrid of rectangle steel and tube - I have 1 3/4" DOM in hand and the tubing bender mounted. I am nervous because of the scale of it. But by modeling everything beforehand I should make less waste and mistakes.

I am hunting for a driver side drop 27 spline NP241C... the later the better. I already have a '94 32 spline so I could settle for a 27 spline input shaft as well. Oh and an aluminum radiator that will cool an LS. These items need to be modeled before I would start building...
