I just bought an 87 D250 5.9l gas. I have searched high and low for a passenger upper control arm. The one on the truck has rusted through. I keep reading about differences between 3800 and 4000 axles. Mine apparently has the 3300. Some I have found online has the cross bar that has 2 bolts to the frame. I just looked and mine doesnt have this. Any advice would be appreciated. How to find one, what, or if any other model will fit?
