Not sure yet. I pulled it out from the barn lot back in 2001. Got it running again and played in the mud with it a bit before parking it again. Needs all new brakes and suspension rebuilt. maybe 1200 miles on it since the rebuild in 1988. The thing got parked cause the 1989 ram 350 Cummins came about. The 78 gets maybe 6 mpg with 4.56 gears that were swapped in. I have the original 4.10s that I plan to go back too. That and the granny 4 speed plus All time 4x4 doesn’t help.
