I put it into gear and it dies.

The female terminals have a barb on the backs.
To remove the females, use a flattened cotter pin, tiny screw driver, or the tool they make for it to depress the tab while pushing it out.

Those above are Packard 56 but Chrysler ones work the same way/

Sometimes they are interchangable. Sometimes not and they won't fit in or they will be too loose in the connector made for the other.
When installing them make sure the locking tab is raised.

ok, I see how that works, that is way simpler that I thought it was going to be.
after I solve the original issue that this thread was created for I will go back and re do that connector. (seeing as it runs and I don't want to mess anything up trying to fix it)
Tomorrow should be the last day of trying to fix this issue. I have the whole day to work on it and now the timing is correct, there are no more vacuum leaks, and I have the vacuum gauge for tuning the carb.
hopefully it will drive tomorrow and i'll get a video for you all.
