I dont have a good answer for that. I know the aftermarket vendors sell clips that aren't even correct for the hardtops' windshield reveal mouldings.
I have the lower stainless piece from a hardtop that I plan to use on my vert with the original vert gasket
Will I need to alter the profile of the vert gasket ? Will I need to alter the heigth of the clips? Will I use something like coax cable to substatute the lock in the gasket ? I hope I will be able to answer these questions someday.
