1980 Rearend will it fit in a 69

[Woody]

Thanks for the replies so far!!

Now for a little more details. My 69 has the orginal 3.73 12 bolt with the axles (& front drums) redrilled to 5 lug. However I am about to install 5 lug disk setup from a 71. I'm running 8 x 15 Ralleys all around and want to use 71-72 axles to widen the rear as they sometimes rub the inside of the rear tubs. I have looked at a couple of the axles only for sale but i'm afraid that the cost of shipping will make them more than they are worth.

So yesterday I ran across a craigs list ad: 1980 posi-trac 12 bolt rearend out of a truck. So would the guts from this rear fit in mine?? Swapping the mounts out is more work that I want to get into. But if the innerds of hte 80 axle will work I could do that easy enough.

Thanks Again!!
