According to some info sources rear axel is:
H2
'73-'77 3.50 3.6M Ford Limited Slip
'76-'79 3.50 3.75M Ford Limited Slip
On that same list 22 by itself....
22 '74 4.88 7.4M Dana (Spicer) 70
'76-'79 3.07 5.3M Dana (Spicer) 61

Using H2 for the rear and 2 for the front:
H2 is '73-'77 3.50 3.6M Ford Limited Slip
'76-'79 3.50 3.75M Ford Limited Slip

2 is '73-77 5.5M Ford 5500 w/o power strg.
'78-'79 Roll bar Ford w/o power strg.

But a F150 should have a 1/2 ton 5 lug 9" rear axle....not a dana 70 or 61 AFAIK and a 5 lug Dana 44 up front.
