This truck is one of 74 D150's build by Dodge in 1978 with the 440 engine. It is original in appearance except for some updates and additions such as a Gear Vendor overdrive, later style mirrors, Aftermarket highback seat and roll pan replacing the rear bumper. I also updated the 8 track player radio with a newer style CD player and rear speakers. Since I use it for towing, I replaced the clock with a transmission temp gauge and changed the 3:21 gears to 3:91 so the torqueflite transmission don't have to work so hard. Gas mileage still sucks!
