Dallas - Rattle? Not when closed for sure. When they are clipped open I think they may have swung free once or twice when the boat was jarred hard enough. I don't recall for sure but I seem to remember clipping them back once or twice. Its just a little stainless ball & tongue clip on the side of the footboards that clip them open. They don't really rattle at all or at least not enough to notice.
Man what a difference after dark or in the morning though. Kills just about all the wind in the front seats at least. The rear bench - well I don't sit there so . .
As for the install, I included the pics which are of crappy quality but should do.

OK. So with respect to installation nothing really complicated here. The hinges are simply screwed to the hull liner so the doors fit into the recess moulded into the 210 liner in the walk through area. There is a wooden backer embedded in the hull liner. You can see the backer if you pull back the carpet glued to the opposite side (inside the bowriding seatback cubby - under the windscreen if that makes any sense)
Door folded back into the recess in the walk-through:

Hard to see but the backer for the hinges is under the carpet blended into the 'glass and you can just barely see the tip of one of the screws poking through half way up the carpet where it is folded back:

Now for measurements, Uhh these are difficult from all the rounded surfaces but -
From the floor up . . . and on an H210 . . .
**Please use caution in reading measurements from the images - they can be deceiving due to the angle from which the picture was taken** I included the tape in the pics to help describe what I am trying to write, but sometimes have difficulty explaining it correctly.
There is a 1" gap from the bare floor (no carpet) to the bottom of the mounted door. You will need this much space to clear the carpet and snaps as they open and you may not be able to go much more than this without interfering with the windshield - remember that you need space between the door tops and the windshield bottom for canvas with snaps to slip between so 1" from the floor seems just right. I remember fishing the bow canvas through the gap on a couple of instances though I can't recall why I wanted the doors closed with the canvas on. Still it may be nice to be able to do for things such such as stashing your goodies if you're beaching or something.
As for where the pre-drills were made for my hinge screws . . . they appear to be 7/8" apart per hinge -
The first hole from the floor up should be at 6".
The next hole should be at 6 7/8" (from the floor)
The next hole should be at 26 5/8" (from the floor)
The last hole should be at 27 1/2" (from the floor)
Note that these measurements are as installed on my boat and may not be the same
if for some reason your hinges are mounted on a different spot on your doors than they are mine (doubt it but we can check when you get them).
Bottom hinge measurments were made like this and note there is a spacer behind the bottom hinge:

Here is the continuation for the top holes tape still on the floor and note there is no spacer on the top hinge:

When the door is folded open there is very little gap as it fits into the recess. looks like it is only about 1/16". The holes appeared to be about 1/2" from the edge of the recess.

And the last picture shows how the doors do not really sit flust at the top with the cowling(?) - they actually appear to sit a little low. This pic should actually measure fairly correctly if you wanted a distance from the top.

Hope this helps out but I am sure you will see its not really too complicated when you get them in your hands. I always have my doubts too - when it comes to drilling into my baby. If there is anything else you'd like to know specifically like the actual size of the door pieces for example just ask.
