In the process of reupholstering my stock seats. After removing the torn covers, destroyed foam, and burlap, I discovered I had a busted spring beneath the driver's cushion. Since they are virtually unobtainium, I decided to take a spring from the middle seat cushion (far back) and transplant it to the driver's seat. I then cut off all but the top ring of the broken spring. I retained the top portion of the spring , so I would be able to join it to it's neighbors as they connect to one another. Beneath the ring I placed a chunk of medium density foam topped with heavy duty underlayment. Probably could have just placed the chunk of foam beneath the busted spring on the driver's seat, but I wasn't sure how much support it would give. So far, it looks like it is going to work great.
