Al your spacers should be OK, this is from the LVVTA standard
Wheel adaptor location
2.5(5) A wheel adaptor fitted to a low volume vehicle between the hub and
wheel assembly to affect a change in the wheel stud pattern, must locate
with a close tolerance fit using the centre spigot or tapered wheel nuts or
bolts:
( a ) the adaptor against the hub assembly; and
( b ) the wheel assembly against the adaptor.
Certainly wheel spacers (like slip on type) are required to locate on a center hub, but bolt on type (adaptors) are OK without them. That's the way I read it anyway.
