38 1.5ton Look at other big trucks for shock mount ideas,you can make your own using angle iron. Go to your local big truck suspension shop and ask them,you'll likely have to buy some new axle u-bolts anyway. On the angle iron you may have to widen one side by welding on flat iron so it will fit your spring perches. I don't think they specify front/rear on truck shocks. You'll also need to drill some fairly big holes,and on the frame be sure shock can't come loose and (woller) out the hole. That is hard to fix !! I just use over the counter Monroe's rather than expensive big name shocks. One other thing is rebound I just count on the shock,don't jump it much like they do in San Francisco in the movie chases LOL.
