Right. But as Ryan explained, going larger than 1.24" t-bars was not on the table for them at that time. We know its been done ('70 transam e-bodies) and its in the Oval Track book for banked circle tracks. If you can get the parts, or have them made, its still doable (withtime and money). But anyway that's way off track (so to speak) for this guy. He wasn't asking about building a competition car, just a pro-touring look and maybe some occassional autocross. For that, there's no performance or economics advantage to go to coil over.
