Snake Oyl in Texas restores factory seat belts - I have 3 sets in my 62’s done by them.
I have pictures of my restored factory 1962 seat belts and my used “sets” of 62 & 63 factory seat belts
They polish/restore the top of buckles, rechrome the bases, rechrome the original tongues and install new 3 or 4 panel webbing( in the selected color) install a new sticker like the original stickers on the buckles.
For the front seat I send them zinc plated mounting hardware ( from the original belts ) to be sewn to the bottom of the new belts and
I use to mount the belts - the loop shaped factory connectors (zinc plated ) for the fine thread nuts “welded to the bottom of factory floor pans” ( in 62,63 and 64).
62 and 63 factory belts have colored plastic boots mounted over the webbing on the bottom 8-10” “on the front seat belts” I have seen and have black, red, white and green boots on the belts I found to buy over the years.
I purchased a saddle ( brown) set of all original 1963 factory front seat belts with black boots a number of years ago from a local friend.
Snake Oyl sends web samples to you to match color of the restored belts to your interior and a estimated cost to approve.
I just sent in 2 sets of 62 original factory seat belts for the back seat in 2 of my 62’s to be restored.
