The Torx L-key is $4-5 from
www.mcmaster.com- i bought one not knowing HKB provides one. I do not believe Momo comes with one (i had a momo for a while)
As for the horn button, what you see is the rubber covering. There's a small horn button underneath it, but this just has the MAD EURO_TYTE MOMO LOGO on it, haha

There is much more wiring involved, plus, I believe, some soldering and drilling.
The HKB hub was $85, the Momo is $55-60. So not doing the work was worth the $40 to me.
Also, that write up does not have provisions for airbag- it tells you to remove the passenger side airbag, because it will not work.
The HKB hub has the resistor attachment to trick the ECU into thinking the driver side still works, so the passenger one is still functional.
SilviaDriver, thanks for the Nardi info. I think Nardi has a different pattern, so how it affects you is how you center the hub on the steering column shaft. The arrow that points up will be off center, because it was designed for a Momo pattern as far as i kno.
S13 charlie:
Don't try to take the hub off without the steering wheel, try to stick the steering wheel back on after you unbolted that nut. Then apply force and wiggle it. I also tapped the hub with a hammer a coupla times. It does take effort to remove, but push and shove the wheel in different directions until it loosens- thats what I had to do. I leaned all my weight on it one way, then pulled it, then wiggled it more, and suddenly it popped off. Be careful you don't smack yourself in the head....don't ask
