Broken seat springs

[grdprx]

I'm redoing the front bucket seats in my 68, I discovered two broken springs on the driver's seat bottom.   
What is the best way to fix this?  Is welding an option, or better to replace?  I was unable to locate any specific replacement parts for the seat springs.

On the plus side, the passenger seat recover went pretty well.  Hog rings nicked me up a bit, but hey, that's part of the experience, right?

I got some replacement spring off Amazon in an attempt to bend new springs.  Why would the factory weld one of the clamps on the seat frame?!?  I believe it's the top photo I posted, the inboard side of the seat.

go to an upholstery shop and ask for 'no sag' spring(comes in a coil) theres different gauges for seat and back so youll have to match up.

Update:  The springs I ordered for Amazon worked out pretty good, I did end up going by a local upholstery shop to get some clips.  There were a bunch of different old cars in there, I'll probably end up having them install my headliner.  Anyway, I'm pretty pleased with how the seats turned out.
