rollbars/cages

[trunnell@mindspring.com (Glenn Trunnell)]

I was wondering if anybody on the list knows of a supplier of roll bars and
cages.  I'm looking for a "real" rollbar and possibly a cage but I'd like
to find one that will allow me to put the top up.  The bars that I've seen
in the catalogs appear to be for show more than protection.  I'm really
interested in building a rally car eventually.  Does anyone know of any
shops that specialize in LBCs in the US?  Thanks for any advice.
