Back to the engine bay!!!
The easiest part to install is the condenser and drier. They come pre-assembled as a unit
The instructions say to remove the grill on your truck. I refused to because my truck has been fully painted and there's a lot to taking a grill off of a '67-68 truck. Although it would have been EASIER, I don't think it's necessary. It might be easier to remove the grill from a 69-72? At least on 71/72 I think you can get away with just taking out the plastic insert.
