Hot Rods Model A spring shims

Does anyone make degree shims for traverse spring front suspension? Been looking but can't seem to find any. Problem is aftermarket crossmember with plenty of clearance at rear of spring but looking like it will contact crossmember at front.

 

These are available through several different suppliers and will solve your problem.
As for shims, you might try a truck alinement shop.

Already have the adjustable perches . Issue is with front side of spring rubbing inside of crossmember. Wanting to tilt spring back a little.

 

As was posted above:
You can get various degree truck shims up to 4” width, and just trim off and use the thick end. Drill a new hole for the center bolt.
Most truck alignment shops have a 5 gal. bucket of take-offs from caster changes. Probably free for the asking.
They are made in steel and aluminum if it matters.
Most truck parts stores will have NIB.

It would seem that shimming the front side of the spring will reduce caster?

 

I have adjustable perches so that's not a problem.

 

I think the adjustable perch will allow for different spring length variations, but I don't see how they adjust caster.
