How did this happen? Strange but true. The 1971-1972 right front Chevrolet pickup fender has one of its two 350 emblem holes punched incorrectly. This causes the horizontal emblem to slope down at the rear. The left fender is correct.
The person that owns this all original 1972 truck states that all 1971-1972 Chevrolet trucks have this unusual feature. You can always recognize an aftermarket replacement fender. Their holes are correctly placed.
