Using diff gears from on year to another

Allright guys. I've got 1974 highboy, I'm going to be swapping in a 1978 f250 dana 44 w/diskbrakes. Now I was wondering if I could use my 74, 4.10 gears in the 78 I'm assuming that I can't but thought I'd ask. If so what will I need to use out of my 74 Diff.

It will swap as long as the 78 is not a high pinion reverse ratio axle (which it may be)

I think it might be also, I posted a couple pics in my gallery of the axle, can you or someone check to see if it is, that is if you can tell just from looking at it.

Thanx

Just look at it this way, if both have the same pinion height (hig or low) they will swap otherwise if they are different, they will not.
