This is Joe's wife. I just wanted to share what I got him for Christmas, since it took me a lot of time searching the internet to find. (I actually wanted to get him this for his birthday in September!) These gun mounts are advertised for mounting rifles on ATVs, but I figured they would work for a speargun on a t-top. They came today (I ordered late) and took about 15 minutes for me to mount. They hold Joe's gun very securely, and while we obviously haven't had the chance to really put them to the test, they are very solid and I feel confident they will do a good job. Here is where I got them: cabelas.com I got the UTV version, which is adjustable 180 degrees. Hope this helps someone else who's looking for a convenient way to store their guns on board!
