I bought a Momo steering wheel off ebay that came with a 300zx boss.

However this boss is nothing like the fitting on the car. Does this look correct?

looks right just like my momo one but you have to modify the steering column slightly so that it fits. you have to remove the standard electrical connection on there

I am going to replace my steering wheel at some point and have found this page at the Z Centre, hope it helps... http://www.zcentre.co.uk/index.php?option=com_virtuemart&page=shop.browse&category_id=76&Itemid=7

 

If you scroll to the bottom of the page there are all the different steering Boss's for the various ZX versions.

Well this is what I have and the boss wont go on because of the horn connection and the lug on the black plastic piece that come out.

 

Now I can remove that black plastic piece completely. Which would mean re-wiring the horn connections. But also that would mean the only thing holding the steering wheel in place is the 19mm centre bolt. The black plastic section keeps the wheel centered.

 

Is that safe to do?

remove the whole thing then remove the centre connecting lug this just connects to the slip ring for the wiring connections to pass up through. Now the horn will earth through the body however on mine i had to swap over the 2 wires in the bottom left off the steering column as this was the only one that would connect with the momo boss so you still get ur horn connecting to the right circuit. then the plastic piece that goes over that mounted with 4 screws will have to be shaved slightly to accommodate the new steering wheel otherwise it will rub. the steering wheel is perfectly mounted by the one nut as the splines and taper hold onto the steering wheel

Thanks Marty, yes I was thinking the splines on the shaft would keep it in place if the nut came loose. Will have another crack when its light.

 

Thanks ZXTT if I can do it without buying another boss would be better and I dont need the cruise control.
