Many years ago, the knob that goes on the seat slider handle in my 260Z broke. I had seen parts on FB from a place called The Unobtanium, and I found they sold their parts on ebay. I decided to get a replacement knob from them. https://www.ebay.com/itm/386245878688 Compared to the aluminum knobs sold by MSA, I figured it was worth the money to get the plastic knob.

The new knob is a dull finish compared to the ones installed in the 73 (and in the 74). I think some of the 3D printing artifacts are visible, too.

I had to heat it up slightly to slide on. While it may not look original, it's much better than no knob. To me it was worth the money.

If you're on FB, you can see some of their parts: https://www.facebook.com/profile/100088893413711/search/?q=240Z

Also on their ebay store: https://www.ebay.com/sch/i.html?_dkr=1&iconV2Request=true&_blrs=recall_filtering&_ssn=theunobtainium&store_name=theunobtainium&_oac=1&_nkw=240z

If you want the one you got there to be shiny like the original, you could probably wet sand and then polish it.  Maybe fitting it temporarily to a shaft and spin that in a drill to sand and polish.

Similar pricing, too. I have been texting Shawn from The Unobtanium, and he is interested in producing other parts in addition to the ones he lists on ebay. It's nice that there are multiple vendors willing to help support the hobby.

Yes, thanks for the exposure to another source!
