Plate Spacer...Right and Left??

[vwnut]

Going to put a set of 1 1/4 " blocks in the rear of my Mazda / Ranger.
There has been some talk of a right and left. Is that on all blocks or maybe just the taller ones to help with pinion angle?
Got a set from the U Pull. Same part # on both blocks. Looked to be original equipment.

Measure them. If they are the same height front and rear it doesn't matter which side or direction they go. If one end is slightly shorter, that end should face toward the front of the truck to raise the pinion angle. Left or right shouldn't matter either way as long as both are installed with the shorter end forward.
