will 3" front drop spring mess up alignment?

[oldblue1968chevy]

If I go a 3/4 drop on my 68 without drop spindles just springs, will it mess up my alignment?

Most people run drop spindles vs springs? Whats the pros of running a spindle rather than a drop spring?

i wanna go spring because of the $ and found a used set for alot less than new ECE spindles.

thanks!

if anybody has a lowered lwb truck on rallys with a 2" or 3" or 4" front drop post pics if ya wanna show off
