Hi Simon,
My car is 356-based and the roll bar is out of a period racing Speedster
(which has retired from racing). There will be some parallels as far as
mounting points and there will certainly be some obstacles. I expected I
would have to go the custom bar route, but this opportunity seems like it
might have potential. Your suggestions are good ones. I keep thinking its
a 1200 pound car so I was hoping that the progress of metallurgy wouldn't
be too big a factor.
I bought a little TIG welder which has been indispensible on this project
(its more like Subaru 360 size, certainly smaller than a Berkeley).
John Keppelman's thoughts were also much appreciated. I will follow up on
the rules and make sure that this unit complies before I move on. There
are probably too many good reasons to let this idea drop. I guess the idea
of running a vintage helmet...oh forget it.
Thanks to both of you,
Clark
