Bumper from a YJ to a CJ

How much different are the bumper mounts from a CJ to a YJ?

I have a front bar bumper from an 95, a guy called me wanting to buy it for his on his 82/83 CJ....is there any difference in the fit?

Will it bolt right on....thanks!

My 86 CJ is a little more narrow...about an inch or so on either side than a YJ,
he's gonna need to drill some new holes...pretty easy.

Wrong, a 76-83 CJ5 has identical frame dimensions to a 76-86 CJ7, the only difference is the length. Any bumper that fits a CJ7 also fits a 76+ CJ5. 55-75 are different.

When I bought my bumper last week, it came for CJ/YJ/TJ.

For the CJ it has spacers and holes that are about 1inch offset from the YJ holes (for the narrower CJ)


If he drills a couple holes and slaps some washers in there it'll be good to go.

The bolt holes are different between the two, the YJ being further apart. The front of the frame on a YJ is right at 0.0625" taller.
So the YJ bumper will fit on a CJ, if the mounting holes are redrilled.
When the bolts are tightend, the bumper will compress approximately the difference in frame height. Unless a small spacer is used.
Bumper length is the same.

Mr Anal here, but are we talking sixty thousandths of an inch or 5/8th of an inch.
I'll defer to BESRK, he should know.
.0625 will need a file, .625 will need a torch.

Not really, i guess if you're super anal about fitting (even though the washers go on the bottom). Sit tight I think I can take pics of the washer set I've got

EDIT:
Pics of said washer kit.

Didn't have a quarter, so for reference thats a AA battery.

.0625" or 1/16" thats a lot of file work on the top of the frame.

Wait hang on. Why would you cut/torch/grind? The bumper is taller than the frame. The frame remains untouched. This is a YJ bumper to a CJ, isn't it?

Sent from my Blaster while searching for the Rebels.

I have no idea why mopar said that, I also thought .0625" was clear.

No, one will need a different spacer than the other. The YJ bumper mounted on a CJ frame has a gap that needs to be filled.
