I know the factory Porsche 935s had an aluminum roll cage, but again, they were raced long ago.  I wonder if the ones still participating in vintage racing have been retrofitted with steel cages...?

I'm not a vintage racer, but I believe they're allowed to run the way they were in the past. They used to allow cages without the tubes welded all the way around too, and I think those cars are still allowed. 

BTW I did the same on the seat mount, welded to the SFCs. Used to be a video of a Honda drag racer that went sideways into the wall and the AL seat folded in half, video was pretty scary looking. I get that some seats don't need it, but I like the idea regardless of whether it's required.
