Anyone know where to get shims?

I'm looking at rebuilding my traction lok clutch packs and at the same time going to be installing a set of pro 50 4.10 gears. Anyone know where I can get a set of shims so I'll be able to install the gears? FMS gears dont seem to need shims but pro50 do, atleast I think so. =/ Any help would be appreciated.

Have tried ford, and B&B auto parts
 
All gears need to be setup, no matter which brand. You should be able to get shims from Ford (though they'll be sold individually), or you can get them in packs from a place like Napa or AutoZone that stack so you can adjust them without buying all different packages.
 
This is a ways from you but Six States Distributing in portland has them in stock. part # 8.8 ford MSK. address 6011 NE Columbia Blvd Portland. 503-249-1010. This is a stackable shim kit for the carrrier only. I dont know the part # on the pinion shims.
