I just bought a 1989 Ford F-series dually with a hydraullic lift stake bed on it. I really didnt see it until I just happend to hear what it was going for and I jumped in on bidding and won it. I assume its an F-350 since its a dually with a stick (fender emblems missing)? The guy said he drove it 150 miles when he repossed it but said it needed to be timed, he said it backfired a little, (I assume its probably the cam) any ideas on this? and what year body parts will fit on this truck? I an going to sell it for about 2250, it drives and bed works fine, anyone need it? Thanks for your time.
