Hey all,
I think I need an upper rear seat frame
71 A body convert!
mine is rotted on the bottom of the top piece

Here’s the rear bottom complete

Top is rotted I was gonna try and repair it but. Not a ure I can.
The rolled rod across the bottom is shot gone!


Bottom length

Height

Top

46 ish across. The top
47 ish on the bottom
23 high
anyone have anything?

 

Should be the same as all GM A-Body convertibles 70-72, possibly 68-72, i'm unsure about the convertible back seat years interchange..

That said, this is not uncommon, especially on convertible rear seats. I fix these by just adding a new 9ga edge wire along the lower edge. You will need to bend 90 uprights at the ends to tie it back into the existing structure. Its all held together with spring clamps, so no need to weld or anything.
It looks like some of your springs are broken at the bottom, those will have to be fabricated as well.

None of that is rocket science, but it will take time and effort.... Which is harder, finding another or fixing?
I would just fix it if it were me- the rest of the seat frame components look to be in nice shape. If it was a crusty rusty pile i would lean the other way.

if you would like to see some photo examples of how to repair those bottom edgewires I can dig up some examples and post it for you to see.

That would help out Ben.
I planned on buying some rolled steel or 9ga wire , where do you get that?
the rest of the frame does look good.
thats exactly it the one wire is missing and two for every spring does attach some how???



My question is how do I extend the existing rotted wires without welding them.

Just found another piece to the puzzle!!! This is what’s left of the main wire at the botto. That rotted it looks like it does not get welded where it attaches to the sides. But like I said how do I attach the back springs to it that are rotted back a few inches?

 

It all gets clamped together. The edgewires, the springs everything in these seat frames except the stamped frame and the rod frame is attached with spring clamps holding two parts together.

So those springs are obviously toast and missing some of their length- you would use any still complete ones to guestimate their lenght, then use general seat spring to replace whats missing, using spring clamps to attach it to the remaining horizontal bars. You would likely need to form up the bends that created the original compression bends. Again, use any remaining existing complete springs as a guide. Even if they are rusted out and fragile, save them to use as a guide.

I'll dig up some pics. I've restored seat frames that literally had the entire borderwire missing from rust before, basically guessing at their dimentions and had them turn out fine. Just a lower rod and a few springs like yours should be easy if you don't overthink it.

9ga rod should be able to be sourced from any HW store, you could also try and find a local upholstery shop and see if they have a 9ga "Borderwire" rod they would sell you. Its cheap, like $5 for a 10ft length. You will need a foot or two longer than the length of the seat, so you have enough to bend up AND inward at the ends. It needs to tie into good horizontal and vertical materials so that it won't just slide off, if that makes sense.

I'll look for those pics to post...

 

Itcertainly does thanks for the time.
I am Dropping them off at the upholstery shop he said he might be able to fix the frame.
will see I’d still like to see the pictures in case he can’t do it if it’s not too much trouble.
I appreciate all the effort!!!
