Title: 3A Front Bumper
Post by: Barry L on June 16, 2020, 01:40:06 PM

Looking for dimensions to fab a new 3A front bumper.. my old one was a C-Channel with snow plow mounts.  Specifically hole locations and diameters and over all dimensions.   Am down to the short rows on re-build.  A quick hand sketch would be great.

Barry,
I thought someone would have added something to your thread by now.  Since my skills aren't up to this level, I purchased one ready to install.  Did you get what you needed?

Still looking for the info.  We have fab capability so hard to spend the $$ for something from off shore.

Not sure how much it costs (raw materials, machinery, tools, labor, etc) but here's my rough numbers pulled off my bumper:

From 1954 CJ3B (assuming the frame/bumper is the same)

length 46"
height 4" (may be closer to 4 1/8")

frame holes centered on rails but from outer edge approx. 9 1/4"

the large hole for crank nut is 1" dia and approx. 21 1/2" from the drivers edge and 1 1/4" up from bottom edge

on my bumper there were 4 other holes (don't know what they're for) and slots for a license plate on the passenger side.  There are also curved ends (very slight - don't know how to measure that) on the outer 3'-4" of each end.

Another option:

down near the bottom, US made, $85.

Good luck HTH.
