What Springs ?
 

I have a 70 C10 longbed 8-350 that I put a 2-4 drop on. I re-installed the factory springs in front and the tire rubs the underside of the fender well when I hit a good size bump. I was going to order stock big block springs but I figured I would throw it out here to get some recommendations. What springs do I need and does anyone know where to get a good buy on these ? Thanks in advance.

What size tires & rims, what shocks? Sounds like you have weak springs and or little to no dampening.

Wheels are 15x8s with 255-70-15 tires and stock shocks.

I agree on the shocks and springs being tired. Fresh springs and some good gas shocks should do the trick. In fact maybe try shocks first. You plenty of clearance.
