Backseat driver

Can someone tell me or show me how the rear seat-back is held in place?

Specifically, that bottom of the seat back. I have the 2 metal tangs on the floor board and I see a hole in them that looks like a screw or bolt should be in them. I suspect that is to keep the bottom down and also keeps the seat from rising up and dismounting from the top.

Should that screw/bolt go into something like a backing plate ? I didn't notice a hole in the kickup at the floor pan there. It's covered with Boommat now.

One of those damn tangs broke on me as I was trying to put the seat in place. The rear floor pans we're a bit rusty so I guess the tangs were weakened.

You should have seen me trying to weld in a new make-shift tang with all that insulation and rear carpet and upper side panels in place. Glad I bought a welding blanket from harbor freight months ago!

It's just wire on the seat bottom that hooks into the tangs on the floor pan. The back of the seat bottom is held down by the bottom of the rear upright. Just go get another tang at the junkyard, anything GM from the 60s-90s will work.

I expected that all of this 'back', 'bottom', stuff would be misleading.

To use your phrase, I'm referring to the 'upright' part of the seat. Specifically at the bottom of that 'upright'. (I was calling it the seat-back)

With the extra insulation and boom-mat, the upright piece doesn't exactly pop into place. It's under tension and wants to pop up & out.
My tangs don't hold it in place at the bottom due to that extra tension I guess, and I still don't know what that hole in the tang is for.

That's the real question, what is that hole in the tang for? (I welded in a new tang, as the old one looked to be welded in place also)

Ahhh, definitely one of those times a picture would help.

I'm going to recover the seats in my 65 in the next few days. I'll take pics for you.

Ugh,. Seeing this up close now has me wondering if the Tang is supposed to wrap up and over the seat wire or down over the wire?
These seats have never been installed since I got the car, and the tanks were pointing upward so I had assumed that was their normal position.

The first picture is the driver side. If I push on the seat the seat wire will be below the Tang.
The second picture is of the passenger side and the longer Tang that I welded in place. It had looked like making the Tang longer would hold that seat wire better in my current situation.
The third picture is just to depict the fingers width of height in the metal divider over the seat top.

By comparison, my Camaro bolts the bottom of the upright to the floorboard.

Yes, the Camaro has the later GM style that stayed the same all the way through the 96 B/D bodies. Off to the garage...

My apologies, I ran out of steam the other day. Moved three cars around, and did a complete garage clean/reorganize. I'll try and pull that seat today!

Thank you for the motivation! Just finished re-skinning the seat bottom. The back seat upper is indeed held in by those tangs on the floor pan. On mine, one is not engaged, and one is bent over and down the hook loop. That's the way I will be putting the back upper when I reinstall after I upholster it.

Could I trouble you for a close up pic of your tang thing?
I got this picture from someone but I can't tell if that tang actually has a small hook at the floorboard end that is catching the U;shaped wire.

No hook at the bottom. Loop sits on floor pan, metal bends over to secure seat back. You may have to selectively cut out some insulation to get that seat back to sit closer to the car.
