Suspension Kit Advice

[chevykevy]

I am ready to buy a suspension kit for the 68 short frame, 1/2 ton 2wd, I am trying to build. I have have recently sandblasted and painted all my frame and suspension stuff and am ready for assembly. I've been looking for a complete kit and have seen them in LMC, Classic Parts(Chevy Duty) and others. The deal from LMC appears to be the best , price wise anyway. I would appreciate any feedback from both sidea of the fence. Good? or Bad? This is a pretty large investment and want to do it right. Also, noticed that LMC is the only company that mentions that GM is now using a larger 9/16 u-bolt for the lower control arms. Noticed the Classic parts bolts look thinner? Thanks for any help you can give me.
