Thank you Cray. Right kind but I think the one I have is a bit older as There isn't a door on the thing on the shaft. The disk on the bracket is a bolt that clamps the shaft for height or depth setting, depends on how you look at it. there is a bolt with a quick wind nut on the other side that locks the bracket that's around the shaft to the folding bracket. I was trying to put it in shaft first and not bracket first, duh...Took a bit but finally had a light bulb moment and got it right. Goes in the boat tomorrow providing it's not raining as I have no overhead weather protection. Here is some pic's of it put together...Name: IMG_20180902_161809.jpg Views: 317 Size: 93.9 KBName: IMG_20180902_161837.jpg Views: 303 Size: 98.5 KBName: IMG_20180902_161842.jpg Views: 311 Size: 118.3 KBName: IMG_20180902_161848.jpg Views: 306 Size: 113.2 KB.
