Sorry if this is not the correct place for this. I am looking to put a FD spec roll cage into my 06 Coupe. I am having trouble finding the materials needed to build the cage. I have never done this before am i am not sure how to find the specific rolled mild steel of:

Tubed metal :
Roll Cage Material must be Seamless SAE 1020 or 1025 mild steel tubing, DOM, and or chromoly.

All roll cage tubing in the requirements listed below must be a minimum of 1.5 x .095-inch for all materials.

Plate:

Each mounting plate or box shall be at least .08-inch thick steel



Of which non of these requirements seem to be very hard but i dont know what i should be searching for to find specifically what i need.

Anybody out there wanna point me to where you bought your materials online for your DIY cage.



Thanks!!!!
