Outbacker OB8-TRI

I have an Outbacker OB8-TRI portable / mobile antenna. I have a tripod and trying to figure out about a mounting bracket to fit on my tripod.

Here is a pic of my tripod. This tripod is also for my 4 element yagi beam for 2 meters.

Any suggestions?

Hard to tell from the photo Erik. Does that top white thing come off? Has it got a threaded hole in the top of it?
