    How do you pull the factory radio out of a 97 gmc sierra?

    I need to pull out the factory radio so I can hook up a red and white stereo cable to the back so I can play my Ipod. Being built in it looks like you would have to pull the whole dash out. Also are there even RCA hook ups (red and white cable hook up) on the 97 sierra or silverado factory radios?

    Are 1971 GMC Sprints' more valuable than 1971 Chevrolet El Camino's?

    Typically I assume El Camino's are more valuable than Sprints. However the 1971 Sprint was the first year GMC made them and they only made 1,030 of that year. So does the rarity of this year make it more valuable than Chevy's same-year model? (assuming both are in the same condition of course)
