71-72 vs 73-8x? A-Arm questions

Gents

Are the '73 & up A Arms dimensionally the same as 71-72 A-Arms?

Meaning, will cross shafts & ball joints for 71-72 models fit in both upper & lower 73 up A-Arms?

Thanks!

6x-72 C10's use a different type of bushing vs 73-87's so the shafts are different.

The 73 and up are easily rebuildable if needed, parts are cheaper that the 63-72( ie ball joints etc) and more readily available too. You will need to open up the u-bolt holes a bit to accommodate the larger u-bolts from 73 and up.
