what bumpers work for a '58 skyliner?

Hi folks,

Wondering what front and rear bumpers work for a '58 skyliner. It seems like the front bumper is definitely specific to the year, but wondering if other full size '58s used this bumper. Same question on the rear bumper - seems like '57 and '58 may be interchangable, but wondering if a ranch wagon or ranchero bumper would work as well or ??

Thanks in advance!
