Yes, I have had a roadster before, a 27 glass unit, channeled 6" over a homebuilt frame. I never encountered the dreaded "cowl shake". but maybe that was because of the 3/4" plywood firewall that was glassed in from both sides. On this current ride, I welded the firewall, cowl top, and cowl sides into a "composite unit" Which seems very strong, however I will take the advise offered and put in a 1" square tube "smile" bar, to help reinforce the cowl and hang the steering column from. It's not only the steering forces input to the dash at low speeds which concerns me, Its the yank on the steering wheel to hoist my big old carcass out of the bucket seat while exiting the dang car.
