Before you made this last post this morning, I had already ordered a pair of 4 degree shims for $17 off of ebay.
I think I'm going to go ahead and install those instead of the 1 degree ones I have. I had a guy tell me that he set up a '57 Suburban with 6 degrees of caster with power steering and it drives great. So, if I end up with 6, I think that will be OK. If it ends up anywhere between 4 and 6, I'll leave it.

The thick end of the shim will go to the rear to increase castor. You want the top of the king pin inclined towards the rear to increase castor.
I also have 6 degree shims in my 57 truck with CPP power steering kit but I don't know what the actual castor would be if measured by an alignment shop. It did seem to track a little better after I put them in but it was not a major difference that I could tell.
