I can't help you. All the ones that came to me were spopken for. If you could get together the need for 5 sets, maybe Joel would be willing to ship more.
From my own situation, I can say these replacement lazerette covers are terrific. No more leakage, and significantly better access because of the larger size.
One comment on the question of what kind of caulk to use: my local fibreglas repair expert said not to use 5200 or silicone. He told me to use Sikaflex caulk. I follow his advice.
