97 Ranger bench seat support rods?
 

Is anyone here familiar with taking apart a bench seat in a 95–97 Ford Ranger and know what kind of material is used for the support rods that lay vertically? I assume it's just very thin steel wire but everything I've found so far is bendable so it won't work. I was able to find the Front and rear rods that those support rods secure to but now I need the thin ones…

The bench seat is sagging from the previous owner and I took it apart and stripped the entire seat with the intention of rebuilding the support grid...


Update: Found out it was piano wire (music wire) that is strung vertically. Ordered a spool, should be here tomorrow.
