CPP grand slam kit or piece together?

[pbmcauliffe]

So I am going to convert the 67 to front discs and dropped spindles, etc and came across the Classis Performance CPP grand slam kit for $1299 (5 lug) or $1399 (6 lug) that has everything for the front end, rear springs and shocks.
Just curious if anyone has used this kit, and how it is.
Also trying to figure out if it's cost effective, or cheaper to piece the same stuff together, by quick price cheacking it seems to be a little cheaper, but CPP has some pretty healthy shipping prices.
