newbie question: dropping a '69 C10 4/6

[downbytheriver]

Hi guys,

I picked up this 69 c10 last weekend, and have gotten to the point where I'm wheeling the frame in preparation for paint and am now considering what I need to do with the suspension. I've settled on a 4/6 drop from what I've seen on here, and a friend suggested air bags in the back. For the front, however, I'd like to do a 4" drop and keep the drum brakes all around. I know all the lowering kits I've seen so far require a disc brake swap. What's the best way to go about this with money being a concern? My buddy said air in the front is a pain in the ass to do right, but I don't want to go hog wild at this point and buy a whole new disc setup.

Don't really want mismatched bolt patterns front and rear either, currently a 6 lug.

Any pros and cons to air vs. spring?

If it makes a difference, I'm doing a 5.3 swap, so the crossmember will definitely be changed. Thanks in advance for the replies. Now off to make my build thread!
