Dana 60 swap

I've had four rear ends in my Duster. I knew what I was going to do so first thing I did was got rid of the seven and a quarter before I even drove the car. I got an 8 and 1/4 and that worked fine. I put my 410 Stroker motor in and knew that eight and a quarter was not going to last and before I broke it I sold it and spent $1,200-1300 building a 8 and 3/4. in about 20 passes at the track I blew the ring gear off the back of it.
Now I built my fourth rear end the Dana 60. I bought a 3/4 ton Dodge heavy duty Dana 60.. for 160 bucks. I sold the brakes and the axles for 40 bucks. I called Dr Diff (Cass) and ordered axle housing ends for I think 75 bucks. I bought axles with green bearings and long studs for 300 bucks I bought a lightweight spool for $125 and I think $50 for bringing pinion bearings or maybe it was just ring bearings..
he also gave me some handwritten dimensions for the axle for my guy to cut and set everything properly...
Also bought new perches.. I paid $300 to have them professionally shortened and the ends welded on the purchase welded on and the tubes welded to the housing.
All in I was $100 less than building the 8 and 3/4... at about 1200 to 1250...
A couple points I'd like to make, first off if the rear end is a little bit heavier the weight is right where you want it over the back tires.. second I've only changed the gears once and I've never had the inclination to try and do it multiple times per day or per week when I had my 8 and 3/4... I've always been somewhere between 4:10 and 3:55's. Love the 355 ...
and knowing me somewhere along the line I have a complete thread with pictures of everything but it's been a while..
please keep me out of the flaming arguments this is just my experience and no one can deny my experience...
