Metal sleeve that interfaces and shims the Momo shift knobs to the tiny little shifter post pf the Miata. (http://www.gomiata.com/timomiad.html)

Great. It is laughably expensive for what it is, but it does exactly what it is advertised to do and makes the Mom shift knobs fit perfectly, tightly, and with no post/knob gap.

GoMiata TightFit MOMO Miata Adapter

GoMiata TightFit MOMO Miata Adapter I had emailed GoMiata to find out if the product would work with the MOMO F16 knob, as I had bought a similar adapter on Ebay which was too large. I received a prompt response from GoMiata, stating that it had been tested with about 15-16 different MOMO knobs, and that they were pretty sure it would fit. Unfortunately, it did not fit. The adapter would only slide into the the knob about 1/4 inch, as the cavity is tapered.

I was able to modify the adapter without a tremendous amount of trouble by doing the following: I went to Pep Boys and bought a M10 x 1.25 x 70mm long metric bolt for 99 cents. The bolt I bought had threads for about the first inch, then the threads stopped, and the diameter got slightly larger. I brought home the bolt and cut the head off using a hack saw. I put the bolt in my cordless drill with the threaded end out, and then screwed the adapter onto the bolt. I spun the adapter using the drill and used 100 grit software to reduce the diameter and taper the threaded end of the adapter down to 17/32 of an inch (this took several minutes). On the knurled section of the adapter, I sanded off almost all of the knurl pattern, with only a small trace of the pattern on the lower 1/4 inch. I periodically stopped to let the metal cool and to try the fit. Eventually I was able to make the adapter fit perfectly.

This is a good concept. I was happy with the customer service I received from GoMiata, even though the adapter didn't fit without modification. I did email them and let them know what my experience was, so they could let future customers know that the adapter would not fit on the MOMO F16 without modification. The adapter instructions do ask that you wrap Teflon tape around the threads on the shift lever before final installation. I happened to have some around since I have an air compressor and have done some occasional plumbing, but it is good to know that you will need to pick up a roll if you don't already have any (probably costs less than a dollar at a hardware store).
