do you know if the flange on the downpipe could be duplicated? I plan on running 2 GN turbos on my sbc in my camaro. I don't know where I'd get the 2 bolt flange or the bolts with the springs to mount it. Otherwise it looks like a ball and socket type flange. I'll have to mount my own o2 bungs then, shouldn't be too hard. Kinda a n00b to these turbos, but trying to learn.
