TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
You know Metra makes kits for this type of thing. You get a metal piece to reinforce the dash and a textured piece of plastic to cover-up the larger holes in the plastic part where the old tw0-post stereo went. It is a pretty inexpensive kit for our 3rd gen trucks and looks factory after the install. I did it on my '77 when I installed the Pioneer DIN stereo with the iPod and Bluetooth. Gonna update the Crew Cab soon too with a new stereo.
