I'm not sure where you're located (Chicago area?), but if I has this issue, then I would take my Cobra to McCluskey in SoCal, Olthoff Racing in North Carolina, Stewart Hall of Hall Fabrication in NorCal or Billy Andrews in New York and just let them fit you and make any seat/pedal/steering wheel modifications necessary. I'm sure there must be some racing/resto "guru" shop near you that could do it properly.

Even ERA in CT and Kirkham in UT could help with any mods, but their schedule may booked for quite a while.

The pillow idea sounds awful to me.
