I've been driving it quite a bit, mostly just short drives around town because of the 4.56 gears. It's a fun old truck but no plans to do much else to it for now. I did change oil to straight 50 (with some Lucas) because it has little or no oil pressure when warmed up with the 15-40. I actually have everything gathered to start another 59 F250 4x4 build. I'm using a late 79 running gear and a 460/ZF. I'm thinking about haul the original one out to a ranch 100 miles from here where I rock and fossil hunt and just leave it so I have something to get down to the river with. Thanks for the experiences and opinions.
