Roll bars

["Louis & Laila" <bwana@c2i2.com>]

Howdy All, I would like to make a roll bar that will allow me to race in SCCA
& historic racing, therefore it needs to meet certain minimum requirements,
but at the same time, I would like to build on that will actually work in the
event of an accident. Anyone out there a technical expert and can give me a
hand with advice? Thank you, Lou
