I need a grommet that will fit my 93 pickup's main wire harness that passes through the pass side firewall. I had a swap harness made and they left the 3.4 bolt on "Grommet" and would like to replace it with the correct one.

im assuming any will work from trucks in the same year range, 89-95.

EDIT: 6/28 - Got one off a member here, thank you everybody for your help.
