Default Adding shoulder harness inner guide

Not ready to recover the seats yet ($$$), but my 72 had them replaced many years ago. And while the car has shoulder belts the replacement seats don’t have the openings. Wondering if I’m better off just having the belts route around the seat backs for now? Is there a way to add the shoulder pass thru without needing to recover? Thanks.

If the seat do not have the pass through and they are C3 vette seats they are conv seats and yes the pass through is there, you just need to change out the chrome bezels for a set with the cut outs. In the assembly manual there is a section dealing with the installation as even convertibles could be ordered with shoulder harnesses.

Some of the more thirty members have cut the closed opening on the trim piece. They are pot metal so I don’t have a clue what to use to open the slot. I believe there was some discussion on the Forum a while back. The new ones weren’t terribly expensive.

For the pass through, you'll need the openings like in the picture.



Hope this helps

the rear of the seats doesn’t seem to have anything inside for the rear belt trim Piece to attach to, I can feel anything underneath that could be screwed into. The AIM shows an inner guide piece attached inside the seat frame. Would I be able to feel this from the outside?

You have to install the inner bracket once you pull the top part of the seat cover down. It wasn’t fun, but if you take your time it's not to bad. Buy a set of Hog Ring Pliers from HB, as you will need to remove And then reinstall 8 or 10 “rings” to pull the seat cover down. I put my seat on a work table so it would be eye level. The long trim piece with the slot for the shoulder belt is held on by 2 speed units (with studs), can you say CHEAP. I had to use large wood clamps to compress the foam, as the studs on the trim piece are not very long. I probably spent 2 hours on each seat. I also removed the sliding tracks on the bottom, so I couldn’t remove some rust and add some grease.

Here's what's inside the seat frame,
Both sides of the seat would have the inside opening ready for the rear-insert piece, the backs are interchangeable at this point


The insert piece bolts onto the seat (the inserts are left or right, not reversible)


So it looks like this for the passenger seat



When the rear foam is in place it's hard to feel if the holes are there, even when the insert is not. They would be in these cut-outs





The front insert (on my 72) has knock-out plugs for which-ever side it would go on, or both left in for verts

As far as I ever figured, the chrome inserts were made with one blank and they all had the 3 different numbers cast into them, then they opened or didn't open the knock-outs as required
