I purchased a 1979 Ford F150 w/ a straight 6, NP435, Dana 20, D44 front and 9" rear. Do you have any ideas what gears it has in the diffs? It is still sitting in the bushes as I have not picked it up yet. I am just trying to ID the gears so I know what I'm working with. Thanks.

for the 10000000000000000000 time it's a 99% chance thats its got 350's for gears and its not a dana 20 maybe a 21 but more likely a np205 t-case

Ain't it possible to have a np208 case in those? Or did they start later?
