So this is what Ron said in regards to the possible GB mix-up:
"
No I am still planning on 10 total GB kits. However because of the strict tolerances on this kit, I have to start with more kits than planned and usually will loose a few on the way. I plan to start with 15 kits and end up with a dozen "good" kits that I'm willing to sell quality-wise. Although I received many calls for that shifter and some promises to purchase, I do not think I have received an actual order for that 11th kit though. If there are more kits available after the production run is completed, I will contact you and see if anyone on the forum is interested in buying the over runs."
Therefore...I must contact Z4 Villalona to double check what exactly he did
