I need a project for shop class, and i need SFC's. So how hard would it be to get some rollcage tubing and make my own SFC's? Where do aftermarket ones bolt/weld to? Any info would help, especially pictures of homemade or aftermarket SFC's....thanks

 

Do a search and start looking on this board, there is a crap load of information here and one or 2 good pics...

 

save yourself a lot of extra work and effort and use square or rectangle tube and not round. it's easy to do, get under your car and take a look and you'll see what you need and where you need to go with it.
