Radius arm length also says a part in leverage applied to the shock. Close to the tire means nothing. Is th shock straight up and down , played over towards the engine, towards the front or rear of the truck? All of these factors and then some play into spring selection and shock valving. You can have two trucks that are identical when it comes to springs and valving. But, weight distribution and leverage applied by the beam and radius arms will have drastically different handling characteristics.
MR=(d1/d2 so close to the wheel means a lot to me. Take ACF in consideration. Think I’m going to mount the shock leaned over the intake manifold. No. TTB trucks are close to 1:1...... 90* or close off beam at bump same goes with radius arm. Therefore shock will be leaned toward engine slightly and torward the firewall slightly. Quit will your wise guy shitt. I asked a simple question for those willing to help with experience. Not mumbo jumbo.
