1975 Argosy Printed Circuit 895493
I can't seem to find a printed circuit board for the instruments on my 75 Argosy 26. The part number above is clearly printed in the plastic but none of the stores I have checked recognize the number and the circuit boards they list are not the same.

For the dash instruments?
Mill Supply had a batch made (I bought a couple) ( https://www.millsupply.com/stepvan-parts/) so maybe worth contacting them.

Mill Supply says they bought out a company that had some of the printed circuits but all sold out. Suggested "Custom Instrument Panels" but they don't know where to find one except a wrecking yard.
Does anyone have any ideas. Repair is not an option. I tried.

The open is in the top right edge.

Right... that's not quite how posting pictures works, nobody but you can access things on your computer
Try clicking on the "go advanced" button, then on either the paper clip icon up top, or "manage attachments" on the bottom
A little window will pop up, click "select image", then navigate to that image, then click upload
Wait for it to upload, when it's done uploading, you can click "close this window" to close the little window, add some text on the original text box, and click "submit reply"

It is just 11 connecting wires with no circuitry at all, but 8 of those wires provide the contact to the bulb holders.

It's a flex-pcb
Fortunately in the last few years supplier accessible to small fries have started popping up
Interested to see pictures of the damaged unit, should be repairable or workaroundable I'd think, I've fixed one or two of those

I usually just take a piece wire wrap wire and solder it from one contact to the other. Just have to be careful with the heat. Pre-tin it first. Then a bit of hot glue will hold the wire in place.

The bulbs have no power and the water temp and amp meter don't work. I'll order some copper tape and see if I can glue the copper tape over the open spots. Thanks to everyone. More later...

Ive had good luck with carefully exposing the copper (scraping away the soldermask) and using a conductive silver paste/paint pen. Not sure it would work perfectly for automotive applications. First thing I'd try is exposing the copper back at least a few millimeters on each side of the bad area, clean/flux well, and solder a small copper jumper, then after testing continuity, use a few small drops of epoxy to keep everything held stable

You can also pick easy big areas anywhere on either side of the break to do the soldering
My hopes aren't high for copper tape, especially as a long term solution

Solder jumper wires from connector point along the broken traces, glue down with epoxy. Try to keep it thin so it still fits. Use a multimeter from end point to end point and flex the circuit gently to find intermittent traces. Tedious, but doable, especially because the flex circuit is transparent enough to trace it out.
