Thanks, do you know which axles we have under our 5vers? I will use the distance of load to shock load and double it for finding the right shock. May add 1" both ways. 1/4" maybe 3/8" plate is all that is needed other than the gr 8 bolts, etc. Once the plates are made, should be an easy install. Worst part is jacking up the trailer and taking off the wheels.
