I actually got a set of EBAY for an extra to do this to. I did this mod probably 5 months ago and everything works like a dream. I have an 6k KID kit that I've been running for about 4 months and its a perfect set up.
The only difference that I found was that the OEM set used 5 torq screws (I think) and the set of EBAY had phillips screws instead of torq screws.
I can did up the seller if anyone is interested, but I believe they were right around the same price, maybe a little cheaper than $250
Here's some older pictures, but still looks the same
