just an idea but if the part cant work because of the mounts, would it be possible to do something like this. as the part will still fit to the mount and overlap the connector (basically square off the ports, overlapped the old mount over suggested new one on pic) ?
new to this so heres hoping… plus dont know if i’ve built the svg correctly, as no defined copper layers lol still learning.
after re-reading , are you saying its not possible to add any slots?
