TimFBsucker Posted May 8, 2013 Author Share Posted May 8, 2013 I have bee keeping an eye on it the last several years as I have the mate to it. And also the fact that I grew up around it. I could have made an offer on it last summer but wasn't in a position to do so. So when income tax time came around I called to so if I could make an offer on it and it was just listed on Purple wave. I hope to have both trucks going some day.So far this truck is still in pretty good shape for being 30+ years old. The doors still close like new and even the cigar lighter still works. The interior is ok but a lot of cracks around the screws from being over tightened too many times. The brakes are like new and the front drums still have the black paint on them. It has 182500 miles on it. Quote Link to comment https://www.bigmacktrucks.com/topic/31085-oil/#findComment-182358 Share on other sites More sharing options...
