72 C10 with static drop

[rmcc]

New to the site and wanted some advise. Currently I've got 2.5 dropped spindles and half to 1 full coil removed from front. Don't remember exactly as it was done back in the early 90's. In the rear I've got dropped coil springs, I believe they were 4inch drop.

So it's 2012 and I'm ready to make the ride a little better. I'm happy with the amount of drop. My front control arms are needing new bushings and shafts so I'm thinking new tubular control arms. Also considering beefing up the shock mount area. I see CPP has some brackets for this. In the back I'm considering going the way of a C notch just to make more room for axle travel because I have felt the axle and frame impact(not good) and it also badly needs some shock extenders. The adjustable pan hard rod is also a possibility.

With all this said, what companies are providing the best service right now? I've been reading about several different ones on here. Any advice would be greatly appreciated.
