Rear bumper bracket/braces - Jim Carter

part # 3700438 Front Bumper 47-55 1/2 and 3/4 ton
part # 3700438 Rear Bumper 47-55 1/2 ton Single Unit Body (panel body)

From 47-55 the center hole on the rear bumper served no purpose.

What was the purpose for the center hole on the front of the 1/2 and 3/4 ton bumper?
