Long boss kit

[FanIsHere]

I'm going to replace the OEM steering wheel with a Momo one that isn't deep at all and I'm after a boss kit that will be long enough so I won't switch on the flashlights every time I turn it, like I do with the standard hubs which are being sold all over ebay (6-7cm). I need something around 10cm.

Standard wheel hubs sold all over e-bay:



I've found some spacers, but I don't know if they are safe.

Spacer 2:


A hub that I have found and it's 10cm long, it's from SAAS and I only find it in Australia, which is expensive too (around €120 without taxes).

Another one 10cm long is from Bulgaria, made somewhere in Europe, but it doesn't fit to the AE86 as the seller said (don't know the reason).

Is there any other provider mostly from Europe, that provides long boss kits and cheep ones? I don't want to use a quick release kit either, the Chinese ones aren't safe enough.
