Does anybody have any idea approximately how much it would cost to do the following repairs on a Chevy S-10:

Put in 2 new cab corners and paint them to match the color of the truck?
Already Bought Cab Corners (those little things were almost $40 each)

Fix a footlong scratch and re-paint a rust spot about the size of a dollar bill on the bottom of the door and a few little touchups?

IDK if the color would help but its QuickSilver

Go to a body shop and get an estimate. Noone can tell you exactly what it will cost.

Like flatlander757 said take it to a body shop for a estimate, or if you can put in some pics so we can get a better idea of the damage.
