Front Drop Question -- Possibly a dumb question!!

[tex_waco_usmc]

Alright, so maybe a dumb question but I am not for sure so some clarification is desired.

I put 3" drop springs on the front of my 67, which has 72 front suspension under it already. (This is going back to when I had the truck in my possesion before, but I remember that the springs rattled around when you lifted the truck off of the ground and put it on jackstands.) I like the height that it is at right now and I dont want the truck any lower than it already is with the drop springs, so if I install drop spindles on the truck will it lower it anymore or will it just allow the spring to fit in there snug like it should be?

This is the first time I have ever lowered a vehicle so I just want to make sure that I do it right before she is completely road ready. Thanks for the help!!!
