How to go about suspension?

[68stepside4life]

I have a '68 chevy stepside. I want to drop it some and need new springs badly. Bad thing is, i have the old DRUM brakes on right now. I dont have the cash to dish out to get a "disc brake conversion" kit (with drop spindles) to help lower my front end.

Would it be wise to go ahead and do a 3"/5" drop just using springs to drop the front that much? and then later going with the brake conversion kit and new front springs(that will be much later ofcourse).
