Yeah, the PDF has the parts number, but the Daihatsu garage locally doesn't have that part number on record - sadly. They aren't great, so I've also dropped Catermoles an email.
According to Daihatsu JP, part # 64330C does not exist. Catterham's have a different part #, according to their explosion diagram of #146... So obviously not a "proper" part number... must be a supplier part number.
Hi rs600942, I got it from http://www.chromdesign.de, fits really easily with 2x mounting brackets that fit over existing bolts. Just looked at current price €159 including tax (shipping extra) but not expensive. Had no problems with delivery. Very easy company to deal with. Hope this helps
