Ed,On my 27 I did exactly what your describing.Front spring mount from S-10 bolted to frame.I widened the rear stock mount by brazing on the additional wiidth with a piece from another mount.Then I reamed the center and bushed it with a full width bushing.Stock rear shackles reamed and new bolts.I swapped the springs front for back to position the axel in the correct place. I did have the advantage of building the body so I tweaked fender position. But not much.The part that is hard to belive is the s-10 spring pads lined up and had 3 degree pinion angle. I had allready bought pads but didn't need them!I just use 2 leaves because the car is so light.Shocks iinstalled as stock with the upper mount being a new 2" square tubing crossmember.It worked for me an rides smoother than I expected.
Ed The springs on the 1989 Dodge D-50 are 2-3/4 inches wide of which there are three
Ed by chance i just went outside and measured i did take the springs off of the rear just before the last snowfall but had them on the edges of the skidoo trailer Eye center to Eye center is 44-1/2 inches.in its relaxed state
Ed these are 2-3/4 inches wide two leaves plus a helper. So my take is you would need something like i attached so that you could run 2-3/4 inch leaves where the eye is only 1-3/4 inches.The first pic I would take them apart and swicth them so that they were offset top to bottom not side to side vette59jdwl
Remember that i said relaxed in other words there is no weight on the springs.Taking that into consideration if you put 2000 lb on the springs they are going to lay down and stretch Maybe just maybe there is someone on the sight that has a Dodge D-50 truck that could measure the springs with weight on them that's the best i can do
