I'm thinking of installing a one piece headliner from our host as shown in the link below. I'd like to get first person reviews from those who have used this product. My cardboard headliner is falling apart. I'll put DynaMat against the roof and get the interior cab light working before I put the headliner. My truck is a '52 GMC 150. * Headliner - 1 Piece Plastic-Classic Chevy Truck Parts
