In need of Pelt mapping help

[milkeyisback]

hey guys im new to this forum and i have a pelt mapping problem that im hoping you can help me out with.

What im building is a truck to go on a little skateboard model of mine, and im trying to texture the hanger (thats the part the wheels bolt to). Truck hangers often have patterns like polka dots or checker board. Ive been trying to use the pelt mapping tool to get things right but no luck.. Every time my checker board comes out all pinched and pulled in every direction.

Ive attached my model below, anything will really help. A good tutorial, or just someone showing me how its done with my model as an example. I will be on AIM all day if anyone wants to msg me.

thanx in advance.
