If you are using your existing pole, the tack line pulley and restraining line eyelet mounts are obstructing the tack guide.

Unless things have changed, you will have to drill 2 holes for the restraining lines (pictured in the previous post). If you wish to run an internal tack, you'll need to install an entrance point. Further, if you are running a single line system, you'll need an additional exit point for the halyard run.

You are welcome to check mine out. It's at Ed's but we are leaving Sunday.
