Is it GM or Dana
 

what 3/4 ton front axles has GM used?
and did Dana-Spicer axles have GM markings on them?

I have found an axle but cant tell what it is
diff cover looks like a dana but has GM cast on the housing

im really lost
any help would be helpful

From 79 (around that year) on up it was the GM corp 10 bolt front axle and before 79 or so it was the dana/spicer 44.70 -up was the open knuckle,closed was 69 -older.
The Corp has more of a round cover than a dana axle.
