Slant 6 and 904 automatic. Very dependable. The speedometer stopped reading the mileage at 62301 because the speedo gear housing bolt broke when I was replacing the torque converter. Not much more mileage had been put on the truck since. It has a hard shift issue and that's about it. Other minor things wrong like the dash lights work occasionally. No major rot rust at all. A very fun truck. The dash speaker had been changed to the oem unit and the speaker cover is back in place.
