NOT! http://www.greatlakes4x4.com/showthread.php?t=114815convert a rear 14 bolt to a front. It is 10 times stronger than a dana 60 and you will be more happier in the long run. You will have to convert it to a stering axle then seal the shafts to keep the fluid inside the hubs, Sounds difficult but is worth it.
the ford has flat tops? never heard of such.NOT! http://www.greatlakes4x4.com/showthread.php?t=114815
35-36's do the SOA setup with a hp44 from a 78-79 F-250 and the matching rear 60. This front bolts in and has flat top knuckles to do cross over steering or high steer.
yes the 3/4 ton late 70's ford axle all have flat topsthe ford has flat tops? never heard of such.
