Title: Body mount Brackets at Rear of Tub
Post by: maximushuntermus on December 31, 2013, 08:06:40 PM

Can anyone give me the dimensions of the 4 rear tub to bumper body bracket locations? I have a new bumper so no holes yet, any help appreciated, Thanks.

I'm not sure if this helps, but..

Measured from the driver side, from the end of the rear crossmember, the first hole in the crossmember is at 4" and the second at 20"

Measured from the passenger side, from the end of the crossmember, the first hole in the crossmember is at 1 1/4" and the second, inner hole at 17" on center.

I measured with the tub and bolts in place.

Well thought that would do it, the rear cross member I bought from Classic Ent. and it seems the driver side is longer from the frame rail than the passenger side, sure seems wrong. here are some photos.(http://)(http://)

Maximush,

That is actually correct.  The original 3A rear crossmember/bumper is suppose to be off center.  There were originally license plate slots cut into the driver side.

O.K. I am seeing a tailpipe on the drivers side?

Rear view

Yes Tim is correct. The distance from the outside face of the frame to the end of the crossmember on the driver side is 13 1/2", and on the passenger side it's 10 1/2"......a difference of 3 inches....Mine might be a little different than yours...

So, I tried measuring from the frame rails...

From the outside face of the frame the outboard holes are each 9 3/8' from the frame.

The inboard holes are 6 1/8" from the inboard face of the frame rail....

Hope this helps....!

Thanks guys I appreciate the help, thats a relief, is the tailpipe not supposed to be on driver side? This was how I recieved it so I just cleaned it up and left it as is.

Yeah mine is up towards the Xfer case so thats wrong, it had a small maybe 5 inch round tube type muffler on it, that should have been a clue huh? LOL, no big deal we can fix that.

There is a drawing on page 114 of the service manual....also there is a drawing of a DJ-3a on page 12 that shows the exhaust.....the DJ routing looks like yours maybe?

yeah Im sure it was done by bubba, when I got it it actually had an f-head in it, so that was probaly done then. Its coming around though, don't expect to get it 100% correct but if I could get it to an 8 out of 10 I would be happy. Its for me only and I plan on running the heck out of it on mostly forrest service roads here in Flagstaff, Az. watching the massive Elk here in Unit 7W. Thanks again for your help.
