Yea, it's confusing. The grill is made from "expanded diamond mesh" and appeared on the PS30 (432). I have also seen them on the S30-S, the stripped down version, and they may have been standard on those models. They never appeared on the North American imports. What Alan was saying is that the original 1970 era part had a finer expanded diamond mesh than what is currently available. Same look. The grills were still available new about 8 months ago. At the time they were around $150. I don't know why they exist. Perhaps the thinking was that the grill offered better air flow for performance purposes, but in talking with Matsuo san, I am under the impression that the design intent for the grill and the front of the car was the horizontal bar type of grill. Oh...BTW...I have one and think they are cool.
