It is cheaper to buy the 3/4" hose barb fittings (Fly High W 737 Fittings) ) but they are not elbows which will cause the hose to kink when you close the locker hatch.
The kit comes with the fly high quick release fittings, OEM 3/4" ballast hose, a 3/4" Y fitting, a 3/4" hose barb union fitting, all the hose clamps you need and instructions. We don't charge for the price of the paper so you actually come out ahead.
I usually throw a 750lb. up in the bow and a 400lb. sac in the walk way. The 1000lb. bow sac will be awesome. If you want to integrate the bow bag it is an entirely new ball game. There are a lot more parts to make that one work.
