I believe we can wrap this thread up soon.
Superatv has been good about communication and have provided good service. In a nut-shell, The lug nuts from Superatv that came with the wheel spacers were a little longer than the factory ones. The band of metal that circles the nut separating the head from the thread on the Satv is a smidgen wider. The taper angle appears to be the same, but the taper length is shorter on the factory nut.
In the attached picture, the left nut is factory, and the longer one on the right is from Superatv.
I heard from Superatv today and they instructed me to install the shorter factory wheel nuts on to the spacers to secure the spacer on to the hub, and to then use their provided longer wheel lug nuts to secure the factory wheel on to the spacers.
I am still a little uncomfortable with threads still showing on the nuts holding on the spacers, but will re-install blue loctite on the wheel studs and hope for the best. The instructions do not indicate any suggestions as to wheel torque specs - waiting to hear from them on that. The manual indicates the wheel lug nuts should be torqued to 98 ft lbs.
Thank you to all of you that offered suggestions and help. You guys are top notch in my book, and I am happy I joined this forum. Thank you also to Superatv's response.
I did tell Superatv that if my wheels fall off I will let them know. In that event I will be more than a little grumpy.
🤠
