Even the Pantera seats rub the cover.
You can remove the plastic cover and do surgery on the steel sheetmetal bracket that holds the brake handle in place. I don't think that you can completely eliminate the contact.
The Pantera seats fit the cabin the best. Varying from that puts you at your own risk.
Corvette seats fit a Corvette.
You also may be able to shim the left seat track higher then the right to tilt the seat a little.
