OK, OK, alright already!!! Mark answered my email with a photo showing where the hole is on the side. I told him you guys would never let me hear the end of it! Never having had a hold down, I really was clueless as to how it was installed, and never did notice the hole on the side. And the other one looks to me as if it is made to insert the J end of the hook and give it a half turn so it can be tightened down. As for the battery, it was cold in my garage, and I just dropped it in quickly for the photo. I did indeed put it in backwards. Don't normally run it that way. Now I just need some kind soul to sell me a tray! I do appreciate all the comments. If it wasn't for the forum, I wouldn't even know there was supposed to be a hold down. Thanks to all.
