Yep, the flooring goes under the sides and the 2 outside panels are attached under the vinyl. jmo
Here is my redu
In pic 049, you can see where we unscrew the floor panel covering the fuel tank, those screws were exposed. But on either side the screws are under the flooring.
Pic 093 even tho you cannot see so clearly, the carpet needs to come up. The floor carpet runs across and up the sides then tucks under the upholstered side compartments.
Pic 111 shows that.
The flooring under the helm and into the bow runs all the way thru. Then the live wells and upper bow deck in planted on top.
I got a lotta pics.
