Fabricating complete rear suspension

Sup everyone I thought I would post in this new and needed forum.

As the subject says I'm fabricating everything for my rear suspension which will save me approximately 1000 dollars(wow thats alot). I have already boxed my rear LCA's which was easy but I am going to step it up and build tubular LCA's, I don't really need them but they look much cleaner. Including relocation brackets.

Next I'm building a tubular adjustable panhard bar which again will be pretty easy. The torque arm and SFC's won't be so easy though. I'm wondering if anyone has any suggestions invovling building the SFC's. What I will be doing is following one of the manufactures size and shape but of course do all the appropriate measurements. Included with the SFC's I will incorporate a trans crossmember so I can have a more stable place to mount my Torque arm.

Any suggestions would be great and if anyone has an opinion on who's SFC's or Torque arm to replicate.

Yeah I've been compliling pics and info off the web about them. I like the tubular style the most out of what i've seen versus square metals.

i prefer the square tube by far over the round, plus the square is much easier to fit and weld i believe.

I figured the square tubing would cause some clearence issues but since we already have a tube bender I'll probaly use the largest tube i can reasonably fit under there.

Those are likely just spacers so they could mock it all up without having to put the shocks and springs in the car.

They can also build it all at ride height that way, instead of having the suspension hanging down like it would if the springs were in.
