so i have a 53 1420 (was told its equivalent to the 3100) 3/4 ton shortbox pickup,with 4 on the floor and radio
A 3100 is a 1/2-ton, a 3600 is a 3/4-ton.
The shortbox sounds like you have a 1/2-ton, but I thought Bobb recognized your model number as a 3/4-ton. Something in your description doesn't add up yet.
No worries, we'll all here to help you sort it out.
Rear bumpers were not installed at the factory on most US made trucks. I don't know if they were standard on Candadian trucks or not.
What are you looking for in a rear bumper?
