Pcb to fit 14 way connector

I had a look at these but couldn't find one that had drilled holes that you could solder a wire into/onto - they all seem to be just pads? Or have you seen anything more useful?

I was just going to solder to the pads but I guess you could use an edge connector permanently fixed to the board.

It would also be relatively simple to drill 1mm holes at the ends of each land for mechanical security before soldering.

Since I have PCB making equipment (and plenty of time) I would be happy to help members out if they want an edge connector similar to the one below but with an additional second row of anchor holes for soldering cables or I could change the design to accept screw terminal blocks.

@dafabv  I just signed up to this forum because of this thread.

I have recreated this board and edge connector in Altium but I need to confirm the mounting hole locations before signing off. I reverse engineered the PCB from the photos shown by CJH earlier in the thread. I was planning on putting it up on Github for all to access. I am using surface mount parts however I chose ones that are physically large so they are easier to solder. Once it is finished, I can export it to ASCII file format so many other PCB design tools can import it. I was considering replacing the wiring bundle with an IDC ribbon cable for a much cleaner installation but I have decided to make a flex circuit (foil) replacement for the 86+ right now. I prefer this route as one can still use the original bulbs or their LED equivalents and less connections to break. Once completed, I will make a pre '86 flex.

I ordered a PCB replacement kit from Chris (CJH),
this kit is really great, he's a genius!
But as you know Chris is not coming back :(
I would like to know if anybody here can reproduce the same PCB kit as Chris to make?
