what shift knob fits the miata short shifters from ebay?
 

I bought one that said it would fit a miata shifter but it didnt fit my short shifter.

Probably a Miata knob.

tried one that said it was for a miata so i think im gonna try one for an fc

probly an ebay knob, try s5 or s1

Miata thread pitch is the same as the later rx-7 (S5+), M10x1.25 unlike the earlier rx-7 (S2-S4) thread pitch of M12x1.50

S1 is M10x1.25, the same as the S5 and miatas
81 to 88 rx7's are M12x1.5

So s5 is what like 89 - 92?

Correct.

or, ANY MIATA KNOB!! LOL!!!

get a universal knob that you like. I only use Razo stuff..

K here's the whole story. Bought a short shifter. Bought a knob that said it would fit a Honda cuz I read somewhere on the forum that they had the same thread patern as a miata. It didn't fit so I contacted the seller in ask for an exchange so I sent it back. He emailed me and said the Honda knob and the miata knob have the same part number. So I'm having him send me one for an s5. If they have one. If not I guess I'll try to get my money back so I can buy a universal.

You can make this quite simple by just buying one with correct thread pitch. Instead of saying it is a 'honda knob' or 'miata knob', just go straight to the source and buy a '10x1.25mm knob'.
