I just mounted under gunwale rod racks on my 1974 19-6. Rod racks were made of starboard and I drilled into the side and used 3/4" stainless self tapping screws to mount them. I measured a bunch of times then drilled just enough to make it through the 1/8" outer wall (bulehead?). I then poked a toothpick into the hole to see how much clearance was in between the bulkhead and the outer wall (hull?). There wasn't too much room in between these walls. Again, I used 3/4" hardware. I also epoxy coated the holes I'd drilled prior to mounting the rod holders. I've been doing this with all of the holes I've drilled into this boat. I want it to last. I've found that Ace Hardware is cheaper for stainless hardware than Lowes or HD and they have a larger selection; plus a lot more specialized parts. I'll see if I can take a pic of one of my rod holders and post it up here.

Are you saying that there is a liner in your boat? I would have assumed that we're looking at the inside of the hull and there was nothing but however thick the hull is, there. Got any pics of under the gunnel looking up?
