No problem.Sometimes the pins on the wiper arms get stuck,which is why I mentioned the WD40.Adding a Radio is quite the job on these trucks.The hardest part is drilling the holes in the doors if you don't have any power options.As far as the price goes,it depends on the yard,but I picked mine up for $15.Alot of yards like to play games with their prices.If they think you need it,they'll raise the price.
