I did mine a couple of years ago
My frames were in good shape...I just sandblasted them and painted
I got my covers and foam from LMC....the covers were PUI and the foam was from Dashes Direct...good quality
I bought springs on eBay...8 gauge on the bottom and 11 gauge on the backs
I put burlap cloth between the springs and foam on the bottom
They turned out great...nice and firm
I didn't take many pictures but I will be happy to help any way I can
