'71 C10 front lowering

[powerhaulic]

I have had this truck for 20+ years, it was my dads.
Have blocks in the rear for drop, am happy with ride height.
It's time for a front end rebuild, all stock now.
Thinking Western drop spindles, but I also have a complete 73 or 74 front frame clip.
Is there any real advantage to doing a complete front crossmember swap on a '71?
Or do I just fit for the arm swap?
2 different PN's for 71-2 and '73 up spindles, I believe the tie rod is the only diff?

Thanks for any help
