I have a 69 3/4 ton suburban frame which the PO swap the front to disc already. I want to use the frame into my 1/2 ton suburban, can I use the A-arms of the 3/4 and use the ball joint upper and lower of a 1/2 ton to use the 5 lug disc, or do I need to get the 1/2 ton A-arms.

Thanks,

You need 1/2 ton lower a-arms, if you want 1/2 ton suspension.
They are different.
The ball joint hole is bigger in the 3/4 ton lower arms.
