The ongoing Underwood "1 element or 2 element" discussion prompted me to see if I could adapt my unused "second element" that I removed to make my "1 element" Underwood Pickup. (For that, I simply cut off the G side element and adapted it using an old Fishman BP-100 afterlength mounting system, which I really like.)
I only have 1 of the Fishman mounting systems, so I needed to fabricate some way to mount this leftover Underwood element.
First, I had to remove the Underwood plastic tie-wrap connecting gizmo, and chop off the 1/4in. jack.

Then make the afterlength piece out of 1/32in. brass sheet.
BTFW- This took me a LONG time, and I eff'ed up the first one.
(Measure THRICE, and Cut ONCE!)

This is a Switchcraft Deep Panel Jack, commonly used in the BG world for side-mounting the output signal on solid body basses.
I used 3 layers (total) of shrink-wrap tubing to protect the connection and to cover the jack.

Difficult to see in the pics, but I added some felt-like material to cushion the afterlength bracket and reduce the chance of any rattles.
I will install it on my bass tomorrow for a test run, just to be sure it's working normally.
I did confirm that it is producing some sort of signal, uninstalled, FYI.
I need a drink...
Thanks.
