trying to save these parshiyos...

I have a set of old tefillin which are probably at best only kosher bedieved, however there is sentimental value so I'm trying the best I can to try and keep them kosher, even bshas hadchak . The customer has a better, newer pair but wants to keep these for rare emergency use. Below are three photos with the shailos:

1) the yud in uvisharecha. the kotz RT is not quite as long as the right regel, besides both are very short - not really a ches. Are these reasons to be meikel?

2) the nunim if veshinantom and hotziyonu. Definitely something is there protruding, is it enough to fix or is it a nun hafucha?

Would appreciate Reb Moshe's opinion please.

PS The revach from the extra word has holes in it....

PPS Very politically correct sofer, obviously likes both the Arizal and beis Yosef so much he couldn't decide which ksav to write....
