There are very detailed instructions posted here by user doc73.
Did the Sewer Fence Post Holder
I just finished mine following most of his instructions. Only thing I did difference was move it further back under the frame where it's hidden just a little. I also used ⅛ inch flat steel plates mounted inside the fence post with bolts going through them to attached to the frame, meaning no outside brackets. Due to the "hidden" location, I installed 1.5 inch spacers between the post and frame on the working side is 1.5 inches lower in order for the "gutter holder" to clear the sidewall when moving.
Painted the post black and once the paint dried it took about one hour to install.
Many thanks to doc73 for his advice.
