Upgrade my lap seat belts

[GRAND SPORT #12]

I just purchased a 1974 convertible 4 speed car. My problem is that it only has lap belts and i would much prefer a 3 point seat belt with retractable shoulder harness. Does anyone no of a good sourse for this or a good aftermarket set. My other concern if i find a seatbelt with shoulder strap what will be entailed in installation to mount the shoulder retractable assembly or did chevy have a mount position so i could do this install. Thanks for any help

In 1974 shoulder belts were a $41.00 option on convertibles. You may find them available in the usual Corvette parts catalogs and add them to your car. The AIM should show how they install.
