On the heavier trucks with dish wheels, there is a iron casting between the front brake and the wheel. It spaces the wheel out from the brake so that the center of the tire is in the proper position. I have heard this called a "hub spacer", but am wondering what the proper terminology is for it?
Also, in the later (P30) trucks, there were 8 bolt dual wheels (16") and 10 bolt (19.5") wheels.
Were these cast GM hub spacers interchangeable, since they all bolt on to the brake with 8 bolts? (remove an 8-bolt-to-8-bolt spacer and replace it with an 8-bolt-to-10-bolt spacer)?
Thanks in advance.
