A Big Brown Truck visited me pt.4

I got a used 31 spline ford diff that I'll get rebuilt to go with the axles.
The tires I got from Western Mototsports. Seemed like a good price and they're supposed to be inbetween a full drag radial and a normal high performance tire for wear and traction.
 
where did you order your prochamber from?
I want to order a bassani c/b (BX) and an o/r pc but i don't know where to order it from!
shipping to canada seems to be a pain
