Beta Hopper Leaf-Springs 2.0

I've re-built the mod from the ground up. The only thing that's carried-over with no changes is the model for the front shackle-mounts, and that will be changed eventually as its texture looks kinda bad still.

Key changes;

1-Re-stole the pickup parts and made a concerted effort to avoid breaking any textures this time around.

2-Also made an effort to improve the geometry of the springs both visually and structurally. The practical difference is slight, but it's there.

3-Majorly cleaned...
