After my last few days playing around getting the hang of Collimation, i see the potential benefit of Bob's Knobs

But looking at their website, i can find the Secondary knobs for my Skywatcher Dob, but i can't see where the Primary ones are

I've fired off an email to them, but they have not replied

Anyone know if the Meade 8" Lightbridge set will work ?
Its not clear that the Primary's are compatible

Thanks
