Does anyone have any tips or advice for fabricating a spacer block needed when converting from multi to mono?

My differential has perches designed for 5 leaf springs. I am putting in a set of Calvert split mono's so I need to build a spacer to go under the leaf springs to fill in the gap.

Any help is appreciated!

You might try finding a lowering block that is the right thickness. It already has the locating dowels and holes for the springs.

I installed the same leafs in my 67, what i did was go to the local metal mart and buy piece of aluminum stock the right width and thickness you need and then just drill a hole in the center.
