I'm right in the middle of doing this. For a circle burner that dont need to be perfect but I want it as perfect as I can get it. I was not comfortable with paying Moser 3 bills to shorten the housing. I cut 3&1/8" out of the middle on each side. 2 questions: (1) what is the best sander/tool to make sure the cut ends are square (they ain't now) and (2) what is the best way to make sure the housing tubes are aligned when my welder starts on it? Please advise. Moser did shorten/respline the axles for me.

The words " Rear end" and "shortening" just sound perverted.... I prefer " narrowing"

I have done it both ways to Dana 60s, but I did not do the welding. The Ramcharger got both tubes cut and new Big Ford "Torino" bearing housings because my racer is using a Dr. Diff spool, 35 spline Dutchman axles and Ford 11" drum brakes. The ends are chamfered to aid in the welding. The Dana 60-2 that I did for the D100 had only one tube cut and the axle shortened and resplined. The original end for the drivers side was cut off, chucked in a lathe and chamfered. The Dana 60-2 uses tapered wheel bearings like the 8.75", but the ends have 6 bolts to bolt on the brake backing plate and are perfectly round, so they fit the jaws of a lathe. The 4x4 shop that did the job uses a high power Mig welder in "Dual-Shield" mode (gas shield + flux)with great penetration and the normal jig for alignment. These guys do this stuff all the time at www.oly4x4.com. There is probably a shop in your area that can do it too.

Pete do you have a suggestion for squaring up the ends that will get me pretty close. I hate to pay for lathe time on this low buck deal. EDIT Pete I just read your response in the other rear end thread. Well I am committed to where I am at the moment on this deal & I think if I can get the ends squared I'll be OK

I would, and do, check the ends for straightness by having a helper and I use two steel carpenter squares and measure 16 inches out from the housing ends, front and back and then straight up and straight down If there is more than 1/8 inch differences in widths then you should have the housing straightened The roundy round racers like to see 1/8 toe in on the front sides, not toe out They say the housing will bow backwards under hard acceleration Maybe there talking about stock Ford housings, you think
