If you are putting the 84 diff on, then you may have it made. I used a 1980 front diff with matching PS box on 1956 Frame. Used some metal I had to make adaptor plate(s). First 4 pics.
The last pic is the "overbuilt" box mount on the 60 4X4. This is not necessary but I left it alone. I probably should cut off half of it.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
