A genuine Gibson P-90 cover would not fit into the opening in the template. I had to put the template on my milling machine to correct the opening dimensions, the length by about .050" (.025"/side), and the width by about .030"(.015"/side), so that a genuine P-90 cover could fit the opening. Most luthiers will not be equipped with a milling machine to do this, and will have problems fitting the pickup. Once finish was applied, my pick-up openings were still a little tight, but acceptable.
I could have made the template myself for the trouble. Would be a great product if dimensions were correct. I have used other templates and they were fine. I haven't checked the humbucker one that I ordered with this one yet.
