I ran my forward bars out through the hole for the fuse box on left and through the hole for the heater on rt. Ended them right behind the upper a arm mount as per the rule book. (SVRA).
No they are not real high but still feel they will help stiffen up the front clip.
Yes, you should box in the frame horns and tie into the front crossmember.

You have all your gauges above the steering wheel. really the bars are made to fit the interior of the car. The only time that you see the bar up high is in windshieldless off road racing. Above the dash.
redvetracr has a cage not really feasible to do within the confines of a street stock vette

about being above the steering wheel. That person doesn't know what they are talking about. You have all your gauges above the steering wheel. really bars are made to fit the interior of the car. The only time that you see the bar up high is in windshieldless off road racing

The dash bar looks too low. You may have some serious leg damage if they contact that bar in the event of a collision, even with roll bar padding. Are you running the stock dashboard or a fabricated one? I'll assume the cage is pretty much welded in? If not, I would move the a-pillar bar lower attaching point forward with the bars following the angle of the a-pillar. Although we've haven't done a C3, we have done 100's of C5's and C6's and a few C7's. Here is a vintage racing C3 we did the build but not the cage.

thanks for info/pics guys - i did notice some of the roll cage tubes are just welded direct to the chassis on pics above, thats not allowed here in the Uk, we have plate that up first, then tube welded onto plate and plate welded to chassis

Yes, the correct way is to weld a plate to the frame and then the bars to the plate. We got that car with the cage already done and painted, we had to install the body panels and get it running. I don't know if vintage rules are different than the SCCA and IMSA rules, which are the specs we use to build our cages. Maybe one of our vintage racers here can clarify.

I am going to weld pads or plate (receiver) inside the interior and onto the firewall and then a second one on the frame to create a perch later after finishing the firewall mounting! Then take a second plate and drill through it into the receiver plate welded, then tap! Then thread the receiver plate! Then on the second plates weld the tube on after after aligning the front! Then in the same manner weld, drill and tap like in the firewall location!

I would read the SCCA General Competition Rules (GCR), ecpecially the Touring 1 section and the sections on cages, seats, and belts, and safety equipment. Here is a link to it. https://www.scca.com/pages/cars-and-rules
