I am parting out a 67 4 door and sold a dashpad to screenman in FL for 50 bucks plus shipping. He estimated shipping using ups.com and sent a check for the exact amount. I made my own box (for free) which is not an easy task for something as big as a dashpad. I got a shipping estimate and it was another 5 dollars. When the original check cleared I shipped the part and was told screenman would cover the difference. That was over a month ago and i have not heard anything from him. I will chaulk it up to experience, but would advise against sending anything to him until you are paid in full.
