Which axles will fit C20 4x4

[Greasey Harley]

Having trouble with the search bar.
I just got a '68 C20 4x4, It's a decent old truck with no rust and a fresh 350. I'm excited
It has 4:56 gears and 4 wheel drum brakes. I was wondering, what years can I get a set of donor axles out of?
Are the axles the same through 72? Or can I fit a set all the way up 'till '87 (91 for Suburbans and blazers)

Front axles are the same direct bolt in up thru 87 and 91 burbs and Blazers 1/2 or 3/4 ton but after 72 the rear axle will work but you have to relocate the spring Perch but a set of later k/30 77-91 axles are a direct bolt in Dana 60f front and a 14 bolt rear

Perfect, thank you!
