I’ve removed my original Christen double seat belt system to install a Hooker Harness setup in my 1981 Pitts S-2A. The belts are in generally good shape, no issues, just have a date code of 05-81 (and I wanted ratchets). Not sure if they’re worth anything to anyone but wanted to offer them here first. Front and rear sets )m(seem to be identical?) but no hardware. Located in southwest Michigan.
