Axle questions -79 K5 Blazer... with pics

[Charger1973]

Ive looked at the chart but im still not 100% sure which axles I have. Can anyone tell me? I would also like to know if they are good, bad or just average? I dont know too much about GMs... Also the ID sheet in the glovebox says the truck came with 3.73s


Front axle:

Rear axle:

It is a front 10 bolt and a rear 12 bolt. Typical 1/2 stuff for that year. 12 bolt is a little stronger than a 10 bolt but not much.
