I am trying to repair a seat spring that has the end support springs broken on both ends.Does anyone know if the LMC part # 30-3124 works on a on a 69-72 full foam seat? Their website says it is for 67-68. If the part will not work is there another source for the correct part?

This is the type spring you need for a full foam seat . I don't know of anyone reproducing them , Place a want to buy in the parts section or try your local interior shop and see if they have a generic replacment .

Those used to be sold by USA 1 Industries 20308-part number.
You would get 4 springs back in 2018.

I only found this listing from eBay for 2 springs for about $50.

I went up to a hobby store and bought piano wire. I should have gone to an upholstery shop. Didn't cost much, but what a female dog to bend into shape!

Cut up an old box spring mattress to make one . Wasn’t easy to cut out it dulled out two steel bi-metal Milwaukee blades . And it was a bear to bend even in the vise

Does anyone have a photo of the correct spring attached to the frame? I have a spring type frame that I can use for parts. I have removed a few springs from it but I’m having a hard time getting the support I need on the end spring without getting in the way of the foam. I suppose I could both h the foam to get around the problem but I am trying to avoid it.

USA1 Industries has the springs that I use. I also double up on the end springs. I think that is why these are always broken, GM only had 1 per side. It just isn’t enough.

**TKCR** · 01-29-2023, 08:35 PM

I also have the original sized springs if you want to use those instead of the repop end springs. After looking at your seat frame, I see you can only use one per side.
You’re welcome to them.

You’re right, they are not on USA1 website anymore. But that is where I always got mine.
LMC has them also
