With the -3 lower the prop wind clear upper bravo cav plate. You have to cut the back of upper off to clear. I wouldn't recommend it. I have heard of a couple cutting and welding a step up cav plate to fit?
The -2 lower will bolt up to the stock upper with no mods needed. Imco makes a cav plate extension for the bravo to do this install.
Thanks, and Ya I know its will take a bit more work to make a -3 fit, but I am willing to go through the effort. However after looking more into it I need to upgrade to full Hydraulic steering first so the drive thing will have to wait till that gets done.
