Not sure for ur application but jks makes crossover shock mounts.. also thats a pretty simple setup to make just cut you two pieces of plate and measure how far the distance between frame rails (minus your plate thickness) cut whatever you want to use Id use some 1/4 thick x 2" square tubing weld to the plates then drill two holes or more if you want to adjust and then make a mark same distance on frame rails and either weld it or bolt into place. get some bolts to mount your shocks up and your good to go, also make sure your shocks are small enough that when they are lowerd to your new mount you have enough up travel
