I think some of the premium packages with the stock aluminum ball require the .75 adapter. If your stock shifter is like mine, it should probably be the 1.25.
BTW, if you order from grabberpony.com, which I have no regrets about, be prepared to wait a few weeks because each knob is made to order I believe. I ordered mine on Jan 25 or so and got it today. Just a heads up.
Thanks for the heads up. Did you get any confirmation or updates from them in the meanwhile?
Nice 3.31's, I run them too. Although wishing I had gone with the 3.55's in hindsight..
They updated the order status on their website as it progressed and they answered the one email I had sent about the status of my order in a prompt fashion.
I would not hesitate to order from them again, but if you can't wait a month for it you may need to look elsewhere.
i can second this. i ordered mine weeks ago, and can say the exact same. they answered the one email i sent within a day or two and updated the status on their site. would i order from them again? you bet. im going to get a shift knob that is completely custom to what i wanted. kona blue ball, silver engravings (shift pattern on top, running pony emblem on the sides). Cant wait to finally get it in
