A roll cage pic and question

"Last thing I wanna do is, not pass Tech at the track!!"

No doubt, especially that kind of not passing tech that costs $,$$$'s!

"how would you weld that windshield bar all the way around"

Depends on the car and the bars your installing. Generally better done in a car that is being back half'd or gutted to the firewall (where you have the floor cut out completely), so that you can tack the bars together and then drop them down to access the top portion of the welds, also helps to have the windshield out (really should take all glass out if your doing any welding in the drivers compratment for a cage).

Ask me how I know all this.
