Do the screws that hold the grab bar, go into the edge of the vinyl covered deck tray behind it (see arrows)? My Maderna deck came with no pre-drilled holes in this location. Some grab bar screws are not screwing into the tab (image) because they hit the deck wood behind it, saying the answer to my question is yes but before I take a drill to 4 hours of my work just want to be sure.

Holes...
Look like heavy 1/16" to 3/32" pilot holes...some are off center and a couple sort of just grazed the plywood..In first pic you can see a near miss that sort of hit the wood about a third of the way down the plywood...then another good hole nearer the bottom. Better ones in the second pic.

Thank you. Interestingly, I tried 4mm x12mm screws and they grabbed and mildly seated into the tray, I am gonna go with this over placing screws to mark the tray, removing the grab rail, drilling and then replacing the the rail and screwing into the tray. With the 4x12 screws, there was no gap from rail to tray if you look from the windshield, so little downside.
 
Indeed they screw into the plywood. Use as thin a screw as possible to limit the chance of piercing / cracking the vinyl layer, or making a bump under it.

If your screw does not catch/ engage well enough, i would recommend to take a longer screw if it needs to grip better, not thicker for reason of possible buldge under the vinyl..

Yes, this is my fear. If the seating into the tray is so tenuous, it can only be to appose the tray and grab bar and not for grab bar support. If you can achieve apposition without it, then that's what I am going for. Any gap, well one can adjust the "U" metal supports under the tray.

I should add, that it is knowledge and detail like this that is so useful and why this forum is exceptional.................

here's a pic where you can see how it lines up, and 2 pics of two dashes showing that most screw holes are quite nicely set at half height in the panel, but not all of them. you'll have to zoom in on the pics, but definitely the dash labelled "spare" has one screw just left of the instrument cluster (bottom right in pic) which was set high, almost under the vinyl. That is what we have to be careful about.

See that the screw location is actually dictated by the Fjord blue metal flange? If the screw is too high too your liking, then just realize that it ain't forbidden to drill hole at a lower height :-)

Happy to help; I get a lot of help here as well.
It's all one happy family! (Why can't other things in the world not be as understanding as this lot here I sometimes wonder....)
