    dana rear problem and question
    « on: June 30, 2007 - 11:11:23 AM »
    i'm looking for a dana rear for my cuda and i've located 2 close to my house. rear #1 is out of a 1989 dodge ram truck with a trac lock posi 410 gears. rear #2 is out of a 1979 ford 350 4x4 with 410 (it is aleady blasted and cleaned up). which one would be a better buy and what would be needed to do to it to make it work??thanks

    I guess the Dodge diff would be the better choice , the problem I see is that both are likely Dana 70s not 60s , there usually is a 60 or 70 cast into the centerr section of the diff
     I believe there is a thread on modifing truck danas in the archive section

    I took a Dana 60 off a 3/4 ton ford 3.73 SG Trac Loc. I used the ends off an old C body 8-3/4 to make the diff the same width and have the same ends as a stock Challenger. I am about to order 30 spline axles from Moser. I wanted to get the inner seals installed as well so that I could use the stock taper wheel bearing and adjuster setup but the guy who did the work did not install them (I failed to tell him). So I am stuck with green bearing setup but that is the same as the old Fords were anyway. You can also buy the ends and the spring hangers from Mopar. This mod cost me CDN$ $29 for the hangers, $85 for the rear (in exc shape because it had a 300/6 pushing it around all it's life), $240 for the machining/welding and will be around $450 for new axles and bearings. Total about $750US.

    Take note of what CP says about IDing the diff. Looking from the rear. the bottom right strength web (next to the actual differential) should have "60" cast there.

    Unless you have some sort of spectacular deal on one of these rears I have read and found in the past it is just better to buy a brand new one.

    you can call strage or whomever and order exaclty what you want with the gears, axles and everything else for around $2K.

    you wont have to have it modified to fit your car, then buy axles anyhow then move the spring perches and everything else that goes along with an old rear made to fit. By the time you are done, you will probably have close to $2K in it anyhow, and not have as nice a rear.

    I assume that the DANA uses the same measurements.  Chuck, you should move your springs in an inch before you weld your perches on. You can get a 295 or larger in the wheel well if you move them in now.

    Body line                YEAR                  Track                  Perches              Notes

    Make sure you correct the pinion angle with the pinion 4-7* nose down when you weld the perches in place
