I picked up some front leaf springs off a 1985 4Runner, but they aren't OEM. The parts numbers stenciled on top are F-35101R, and F-35101L. They look like Betts springs, but I can't find a match on the number. Anyone have a clue? Yes, I Googled it.

 

Here's a photo. Maybe someone will recognize the little symbol in front of the number.

 

Why does it matter? I'd just install em and see what they look like. Obviously there's a left and a right. Can we see a picture of the entire spring to get an idea of what the free arch looks like?

 

It doesn't matter at all, I'm just curious. There isn't much of an arch at all, so they definitely aren't lift springs.
