how much would I expect to fork out for a dropmember kit?

[SNTOS63]

What up every1! I have a 63 with a 71 front crossmember and rearend off the same truck. I did this back in like 2000 in order to get the 5 lug pattern and front discs. Its lowered okay with dropped spindles, coils, and blocks and coils in back, (4.5" & 6"). The thing is that I now want to slam it with some bags! I want to get a dropmember to gain clearance and get it as low as I can in front and a new crossmember and trailing arms for the rear with a descent c-notch. Now I've got a family, house, kids and all so money is hard to save you know. So if some1 can guide me in the right direction, I'd appreciate it! Thanx fellas!
