Yes, that's what Geo is talking about.  However, you don't want the
rollbar to be too far back because the next nearest point forward of that
is your windshield and the a-pillar.  Personally, I wouldn't trust the
a-pillar and I'd want to have a clear line from the top of the rollbar to
the top of the dashboard without my helmet interfering (and I don't think
I currently have that :(

I *THINK* it would still work.  You'd be able to work the belt around the
beltbar I think.  The belt bar you don't really need anyway.  Mine even
came with an almost serraded edge so it cuts things!  I filed it down and
it still cuts my hands sometimes when I reach into the back for something.

That's what I currently have.  If you want, I can take some pictures for
you Peter

A full cage in a street car would be a bad idea in the event of an
accident.  I'm a *BIT* concerned with the rollbar in an accident on the
street.  For example, if someone t-boned me hard, the other car's bumper
might wrap around the rollbar hoop and catch me and pin me.  Ouch!

If you want to see some more pics/info, I did a quick writeup a while
back:

If you'd like more pics that aren't there, I've got some more out there on
the web somewhere (and I can easily take some more if you specify what
you're looking for)
