You don't need to mess with the engine & ZF but assuredly the entire 
interior will need to come out. There are roll-bar/roll-cage rules, you know; most 
open track organizers follow SCCA's guidelines. They specify wall thickness 
of the pipe to be used (a suicidal racer actually installed one made of 
lightweight exhaust tubing- which would protect about like those giant thinwall 
'show-bars' on jacked-up pickup trucks that never leave the blacktop). 
There must be an accessible drilled hole near the bottom of the main hoop for 
visual inspection of wall thickness. 'Course if you'll never run a track event 
and are just concerned about going sky/ground, you can construct whatever 
you wish. An anti-rollover vent valve on the fuel tank is a real good $35 
investment, too. But the SCCA Rule Book has some good guidelines. Just a 
thought- J DeRyke
