Opinions on POL's 5-lug disc brake conversion kit

[1970ChevyChamp]

Hey all, I was wanting everyones opinion on Performance Online's 5-lug disc brake conversion kit they offer. I am in the process of completely stripping my 67 to the frame. Im wanting to do a 5-lug disc brake conversion, as well as a 4 1/2 drop on the front. I like that they offer alot of other front end parts to replace the old used ones. Just looking for opinions, good or bad. I've learned alot the hard way, just trying to do some homework on stuff before I purchase. If you have used another similar setup kit like this I'm open to hear about it. Thanks!

here's the link to the POL kit
