Dusterdude72
IN MOPAR MUSCLE MAGAZINE
My 72 duster I knew had an 8 3/4 in it and i knew it had recently been built with 4.10 sure grip prior to me buying it but I just recently checked it all out while I was in the middle of bleeding my brakes off and I took pictures and took note of the part numbers.
I have a few questions for the experts as to if this is the most desirable 8 3/4 and if so ....why? anything special about my set up? and anything anyone might think would be good knowledge to know that I had not asked a question about please feel free to mention.
I have seen alot of pictures of dusters that showed how tight there wider tires sat next to there leaf spring and this is not the case with my set up...... I have 275/60/15 bfg g force T/A drag radials and I have about 4 or 5"'s between the tire and the leaf spring on each side.
Now where it gets interesting..... it looks as though there has been some new boxed leaf spring mounts have been added and welded into place and relocated the springs inword? I also see that new perchs were welded onto the axle and I can see where the old perchs sit a few inchs off to the sides of the new ones.
The 8 3/4 center section part numbers are 2070742 with a number 2 above it and a letter A with a circle around it and a large number 2 off to the side .also below the part number is the casting AAPW and 1299? im trying to read from the picture because I forgot to take note while looking directly at it.
so I believe it is the 742 set up. and should have the large stem 1 3/4 pinion.
I am no expert when it comes to this area which is why im looking to fabo for opinions and info!.
the entire under carriage has been updated prior to me buying it and has new bushings,front shocks,tie rods,ball joints,kelsey hayes 4 piston disc front brakes,russel stainless steal braided brake lines,rear end rebuilt...all of it. I am just rebuilding the rest of the car. (resto thread in my signature )
sorry for the long post. just trying to get out as much info as i can , Thanks everyone in advance!
