I don't think he understood the problem. I also PM'd him. Hopefully they'll figure it out.
Otherwise, I think vividracing carries it, so I might order from them depending if its shorter and heavier than stock or not.
As far as height, I'm not sure what the height of the factory one is but I can guarantee this one is at least the same height but probably shorter. The bore goes as far up into the **** as possible, without coming through the top. If you wanted it lower, you can simply cut your shifter shaft down with a dremel and this **** will still work fine.
-billet **** height: 3", weight: 6.0 oz, installed height 5.4"
-stock **** height: 5", weight: 3.4 oz, installed height 6.0"
except for the lack of a boot, it is everything i wanted in a ****. its heavier, countersunk to reduce the throw, the generic brushed look matches my interior, and its affordable. it reminds me of my old team voodoo ***** in my other cars.
unfortunately, i have a problem with my boot. the directions state to cut the boot at the base of the factory **** to leave the boot as long as possible. i can tell you that is NOT enough. I cut my boot 2 cm higher than the base for extra security and it still isnt enough. my boot continually pops off.

if you look at my measurements above, you'll notice that the billet **** is 2" shorter, but the installed height is only 0.6" shorter. thus you need 1.4" MORE boot than the base of the old ****. in hindsight, i should have removed ALL of the leather from my old **** and not cut it any where near the base.
anyone have an old boot they don't need or want?
thanks!

Tried Safari, works ok!

in retrospect, there are several cheap looking boots available on ebay. if i had to do it over again, i would not have cut my stock boot at all. i would have removed my stock boot from the plastic undertray, and cut to fashion the ebay boot. that way, you can have lots of extra fake leather boot and a factory shift **** and boot that you can sell or reinstall at a later date.

The selling point really is the fact that they are secured to the gear lever with screw, so no more gear **** in your hand during fast shifting at the autocross or track.
I had it happen to me a couple of time in very hot weather.
On the other hand if you live in hot climate and park your car outside, the know can get unbelievably hot to the touch, but it cool off in a few seconds under AC as well.
