  1. From what I have found, the lock collar type costs more and takes longer to assemble in production, but it is stronger. The one piece assembly will move out of place easier. Plus it is said that when the screws are tightened in the one piece, they will jack the race out of round.
  2. If the lock ring is not tightened in the correct direction, the inner race can back off leaving it loose on the shaft. Of course, that cannot be done when the shaft turns both ways. There are bearings with an extended race that have 2 set screws in the race that would work in an application of turning both ways. On a steering shaft I don't think the eccentric type will be a problem.
  3. The lock collar should be tightened in the direction of rotation. But the steering shaft rotates both ways! So how do you tighten it? At the RPMs of a steering shaft it probably doesn't matter!
  4. About 1944-1947 GMC 900 series. 6-71 engine.
  5. And beside the paint, the roller skate wheels don't do it for me. Why do they put big trucks on a 1 ton chassis?
  6. Tire damage wasn't the concern. It was to prevent the bumper from hitting the tire and causing the loss of steering control which would result in a crash.
  7. For pictures, do a search here for en510. That manifold would be very desirable to many owners.
  8. I was thinking because it is a dump truck, possibly a stone caught between the duals. But you have probably checked for that.
  9. If nothing else, you could buy a chrome one and sandblast the chrome off and paint it.
  10. It has "very rare Original Fiberglass Front Fenders"? Have never heard of those.
  11. The Mack museum has been closed due to the virus, so it will be a while for an answer if you ask for information. When they finally do reopen, there is going to be a big backlog and it could take a long time for a response. Get your request in now so you are in line. They rely on donations for operation of the museum.
  12. Maybe you can import the parts from Australia cheaper! 😁
