Here is a couple of quick questions on a Dana 60 rear end. I am getting ready to set the narowed Dana 60 housing in the car. I am just going to clamp things together, with the spring perches loose, until I am ready to fully assemble the rear. The spring perches are big time rattle- loose. Check the tube diameter, and it is 2-3/4", not 3". Anyone ever seen this? Or, did I just figure out why it was such a bargin?
Also, what is the corrrect size of the stud portion of the center bolt in the SS springs supposed to be. I have about 1/8" clearance in the M.P. spring perch and the stud diameter.
Thanks for any information.

I always thought 3". All of the specs on spring perches say 3". When I put together a Ford 9" years ago, it was 3".
The only thought I had today is that the Dana was made from a front end housing. Is this possible?

Thanks everyone for the information. At this time, it is what it is. I don't think it will be a strength issue. The tubes are still pretty thick. I have a plan fro welding the perches. I also plan on using a LPW rear cover with the brace kit.
Heck, if anything it will be lighter.
Thanks again, John

What i am planning is to split a 3" OD, 2-3/4" ID tube about 3 or 4" long, and weld it around the axle tube. Then, weld the spring perch to the outsice of the additional tube.

My plan is to esentially weld two split halves of a tube to make a ring around the 2-3/4" Dana tube, which will create a 3" diameter for the perch to be welded to. Imagine two pieces that look like main bearing shells. The ring will be skip welded to limit heat distortion. I am making the ring around go all of the tube so the "U" bolts have the proper contact on the top.
I am just mocking up the rear using some 3" exhaust tubing. I will shoot a picture of the maoc up as soon as i can.
