Give us some info-
Overall length, eye to eye (should be ~55"). Front segment length (should be 20"). Front bolt sizes for the spring eyes (/6& lt. duty V8- 1/2", HD V8 & SS- 5/8", aftermarket could be either). Leaf count would help, too.
Mainly just want know know if I'm missing something along the lines of brand. There's no stamping, all I have is faded paint I can't really make out. But I get how dimensions help.
The one that sits higher I'm guessing is passenger side. Could be mistaken
