I have a 1953 1/2 ton that I purchased . It currently has a Chevy 10 bolt rear end under it. On the drivers side the caliper is on the rear side and on the passenger side the caliper is in the forward position. Is this normal or is there a reason they are not both on the same side? It has gm mid size calipers with parking brake option and both are marked L for left side? Truck was restored many years ago.
