Leaf spring front eye bushing help.

I'm working through a problem with a custom traction control system I'm putting together and can't seem to find urethane eye bushings in the right sizes.
Here's I what I'm doing...
I moved my leaf springs in against my frame rails for some added tire clearances. I did this by modifying the front hangers (moved the stud locations). Now I'm making a modified version of Caltrac traction bars (link type) that I want to tuck inside the hanger because they can't go outside like the normal design. To do that I need to shorten the front bushings slightly to accommodate the bellcrank plates and trust washers that will be on each side of the plate between the hanger and the leaf spring. I'm using new replacement leaf springs that have an 1.50" front eye bushing, and have a 5/8" bolt (ESPO Springs and things 6ply 2.5" over height).
My problem - I can't find urethane bushings in 1.50" diameter, for a .875" diameter tube for a 5/8" bolt. I don't even need them to be the right length - I can make them shorter. They'll need to finish at 2.0" long. I'll even make the tube for in them if I need to.
Anybody know where I could find something like this - I've searched the web and it looks like when I go to a 1.50" diameter bushing it pushes me down to a tube for a 1/2" bolt.
Any help would be appreciated.
Thanks!
