68 Dart Circuit board query

Hi Dana... Thanks so much for answering my question about the washers that are stuck!!
Now, is it absolutely necessary that I remove them and fit to the new circuit boards? I tried removing them, as I thought , as you have stated, that they were simply stuck due to age; however mine are stuck proper, and I fear I may damage the old circuit board if I pry too hard to remove them? Perhaps, IF it's absolutely necessary to have them installed on the new circuit board I could use fresh washers? For now I have just fitted the nuts etc without those washers... Thanks again!
Hi Dana... so today I refitted the instrument cluster, however... I could not figure out how to plug the pin type connectors back in; I tried doing it before fitting up the cluster but couldn't seem to that way, so thought best I just fit the cluster itself, including the steer column etc, and I'll be able to patiently push the connectors on. However, I tried and tried and cannot seem to get them plugged back on; I also do NOT want to force anything especially given I already broke one of the original ones. Just thought I'd reach out and get your experienced thoughts on this, as I'm obviously a bit deflated after all the effort I've gone to restoring the plastics etc, and consequently damaging some of that work in the process of refitting...
