Pretty much pointless doing all the work you have done unless you re-pin the connectors as well. I have been there and done that and they simply need to be done.

Wouldn't hurt to check the switches on the drop target assembly are all adjusted properly as well if they are continually scoring.

Good to hear you have got the auto scoring sorted. At least that is one job off the list, I am sure there are plenty of others though....there is always is.

I have both Pascal and Ni-Wumpf boards in my Sys 1 machines. If you can afford the bit extra I would go with the Pascal board - great boards.
