ES 330 tech area!

I finally decided to upgrade the original PUs for some Lollar 50s, here is what I noticed : the original PUs have no distinct label of origin, they do not look top notch, badly scratched, like second hand stuff!!!!comparetively with my ES 335, the ground wire looks flimsy; even the nuts & thread of the pots might look.....chinese??? So I will get me an RS Guitaworks pre wired kit as soon as possible. On gibson site the P90 are more expensive than the Lollars, go figure.
any opinions about what's goin'on here?????

By the way it is a 2014 custom shop model ,body & neck are perfect l and the tuning machines too, but under the hood, it is quite another story:##
