I know this topic has been covered numerous times, but in doing a search I have not come up with a specific solution. I'm changing my '69 mono leaf springs to Hotchkis multi leaf springs. I understand that the multis are thicker at the spring perch than the monos. This causes the shock to not line up with original lower mounting plate. In my case the original spring perches are a non issue due to using a universal perch. There are no sides to the perches where the u-bolts go thru. These shocks, perches, and shock plates worked well with the mono springs. My question is do I need to modify the shock plates to relocate the hole for the shocks, or is there an easier, off the shelf type solution?
