    does any body know the difference between a dualy rear end and a single wheel diff?

    does a 14ff from a p30 dualy would work(length ,spring pad,etc)
    Around here they are getting reel hard to get . Just have to forget the junk yard because they want to rob u (they ask 600-850$ cdn each.But they are stuck whit the p30 ones.

    Dont even think of going to d60 up front (would have to get a third job!!!!!)

    so any guess???

    The dually 14b is quite a bit narrower than the single wheel version. /forums/images/icons/cool.gif Also the spring pads are in the wrong spot for a K5. Try to find one from a 3/4 ton. I got mine from a '77 3/4 ton. The only thing I had to change was the shock mounts. They hung too low.

    I am running a D70 HD out of a Cab and Chassis Ford...I had to move the spring perches and make shock mounts. It I about 2" narrower on each side than my D60 front. I am running 2 1/2" spacers on the rear, so my track width is about 1/2" wider in the rear. I am builing another rearend with lower gears etc and am willling to sell the spacers. If you can get the dually rearend considerably cheaper than the single wheel, go for it. Another option is a D60 rear out of a 3/4 ton Ford.

    the rear axle is narrower than the single, and a dana from any of
    those will work with some minor mods
