'92 Wellcraft V20 T-top installation

[Gogadawgs1]

I ordered a Dolphin Pro 3 ttop and doing a lot of restoration etc to the boat. I am wondering if I should put backing plates below the deck under the feet of the t top and/or run top plates on top. The deck has a little flex but not too bad. If below should I just cut some access points in the stringers to get plates under the deck? What is your experience or recommendations for doing so. I am going for overkill here? I am super excited about this boat as it is a lot of fun and looking for great memories fishing with my kids on the lake. Thanks in advance for any help.
