Nardi steering wheel hubs interchangeable on cars?????????

[worangejuice]

Hey guys,
I got a nardi 330mm 6 bolt steering wheel I wanna put on my 1988 non airbag E30.
All the nardi/momo e30 hubs are $75+.
I searched for general nardi/momo hubs and there are $20 used ones off of Nissan 240's. So some cars have the same spacing setup for the steering wheel (whatever) but different part numbers or branding (manufacturers,etc.), but some are exactly the same.
So I'm asking if anyone knows another make/manufacturer steering wheel hub that can be used on the E30.
i.e. nissan 240sx,ford,volkswagen hub adapter works on a bmw,toyota,etc.
Like the Ford Taurus sideskirts adapting to the E30 or electric fans etc.
Just trying to be more efficient about spending money is all before anyone chimes in on "just pay for a works/bell quick release $500 setup,well worth it."
Just productive input is appreciated.
Thanks!!!
