Help on P60 drop in build

Hi all,
Building my own P60 with the KD 8x7135 V2 LED Driver 3040mA 17mm for my L2P.
I want a OP reflector. Where is the best place or places to get all the parts with the recommended reflector. I would need the pill, spring, reflector, isolator, XML-U2 1a or U3 thermal paste etc…

Also looking at the 8xAMC7135 (3.04A) (selectable) Mode Driver from illuminationsupply.com. How is this compared to the KD driver?

TIA
