I purchased a Momo wheel a while back and also ordered the JZA80 Momo hub kit.
Supplier sent the wrong kit, had no provision for the clock spring connector, had a brass horn ring instead.
It physically fitted but meant the removal of the clockspring and then the loss of the horn.
I hunted around and found it very very difficult to find someone that sold a Soarer boss. Most seemed to think that the Supra one was different and getting pics was hard.
Long story short, the HKB boss OT-155 fits fine. The supplier didn't think it would fit my Soarer and couldn't confirm but sent me some pics that made it look like it would.
The boss clears the clock spring connector and has a little single wire plug to plug into the clock spring assembly for the horn wire. You need an earth in the wheel somewhere to feed the button.
Hope this helps someone else. I hunted around for a while including searching on here and couldn't find a definitive part number that I could use in NZ.
