Sorry, the "Datsun" patch group buy has ended more than a month ago. You can get them off of eBay though. If you are interested, I'm doing a run of "Hybrid Z" patches. I think the thread is still in the Non Tech forum.
On a side note, the jacket I made gets so many compliments! Seriously! Never before have I worn an article of clothing that sparks a conversation with car guys and gals. I wear that jacket everywhere. My first compliment was at a beer depot, he said, "Nice jacket! Looks vintage." That made all the hassle worth it.
