I bought these at the big-box store ...
Try Lowes, Home Depot, TSC ...
They are aluminum -- 1/2" tubing & 3/8" rod.
used for the upper seat support.
The rod slides into the tube ... buy 2 tubes and 1 rod.
You will have to adjust these for length ...
One end of each tube is mashed down (use hammer & vise) to become a flat surface thru which you drill the hole for the bolt to attach it to the dropout. Use an 8-10" length of rod for each side ... mash down one end of each rod (use a BIG hammer and many hits ... ) The rods are attached to the upper seat support bar bracket (those things you welded on the bracket that poke down ...)
see brackets in the previous post below ...
Up near the top of each tube, drill a single hole. Mark your rod with 1" lines (use Sharpie permanent marker) ... slide rod into tube until line is visible thru hole and drill a hole through the rod
(large enough to accept a small/medium "hitch pin")
It helps if the rod is attached to the bracket & seat when you do this ... so it doesn't rotate on you ... (same same with the tubing - attached to dropout).
This part isn't explained really well in some instructions.
Anyway, it makes it adjustable for a more comfortable ride (no you don't want the seat to be vertical) ... you do want the seat leaning back somewhat ...
You are such a technical kind of guy !! nice hobby Bro..
