basically

you can use group a wheels on a standard hub by using the "group a" convertor nuts,

its a nut with a sleeve, the sleeve goes through the larger hole of the insert in the group a wheel and tightens to the standard stud

i 'think' your is a standard fitment wheel so you would only be using a normal wheel nut !

so, as above, you dont need group anything so get on with it

no tbh, you need to measure the inside diameter of the hole for the stud then we can tell you exactly what you have
