John,
I got my ram mounts from GPS City in Calgary, they deliver to Edmonton and you get your stuff within 3-4 days.
Selection and prices are great.
You can order individual components, or multi-piece component sets like the one you are looking at.
I ordered mine as components. I ordered
two of the ball and clamps rings and one arm to accommodate my set up.
That way - I have one ball and arm on the
front rail of my bow, and the other on the
motor shaft as designed. That way I'm not drilling holes in my deck, and I can use my travel cover and still secure the mount ....... nor do I need a extra long 12" arm. ........ something to consider.
Also, if you are going to mount it on your deck, measure the distance between where the base will be drilled down, and where the shaft "naturally" (without a bend) rides. You may find, if your deck is deep, the arm will be too short - they have several lengths of arms.
Better to be be slightly longer (and angle the arm a little) than to be too short and put a bend into your motor shaft.
These things are designed for shallower deck bass boats, where the distance is only 6" or so from the deck to the shaft, not boats like ours with recessed decks.
Also - there are different sizes bases and mounts - the ram mount web-site has a product configuration tool so it won't allow you to mix ball and socket sizes that won't work properly.
