Rear leaf spring Woes

I have a 1986 f350 4 door long bed with a 460 4 barrel. I have recently changed out the rear leaf springs. The new(used) ones came off a 1992 f250 chasis (it was a tow truck). After bolting ever thing up it seems my axle is back farther than usual (usual being before). Do theses leaf springs normal interchange and what I had prior the wrong ones (since i bought truck used). Or is there something wrong with my installation? Also my rear drive shaft from carrier bearing is now showing blue teeth. and looking at yolk area there is about three inches of new shiny metal instead of the rusty looking? Any help ?

Take the old spring and hold it up beside the new one and see if they match lengthwise and in axle location. I'm betting they don't.

I measured the overall length before installing they were the same length. guess jumped ahead of myself though because the centers are not in the same place. I am going to try and use my original main leaf and replace whats beneath with the new ones. Think i am going try try driveshaft out of the tow truck and see if its longer that would be easier
