Roll bar "side bar" question...

[toofastforyou]

Jack, as you know, I have a 6pt roll bar in my GN with swing-out side bars (which have a mechanism that sometimes tend to get stuck...)
But now that we got my to run into the 9's, I know that I'll probably have to go with a cage to be NHRA legal. My question is this: Instead of having a regular side bar (swing-out or not), can I have a fixed "X" brace instead (like the one shown below of "GUMBO'S blue T-Type I saw last spring at your b-b-q party...) ? I'm slowly making myself to the idea of having a cage done and I'd prefer the "X" over a single bar, but is it going to pass tech inspection?...I guess Brian shouldn't have any problem fabricating one like that...

Thanks,

Claude.

P.S: Is the lower horizontal bar (close to the car's door sill) mandatory ?...not sure...

Thanks Jack for telling me about this "X side bar" thing on the phone today... When the time comes to do my cage, that's what I'll have installed.

Also, are there some other guys here who have an "X side bar" in their car and could post pictures?...
Thank you,

Claude.
