Majesty pots substitution

Hi to all! Question about potentiometers on majesty (monarchy 2018). Some time ago I was found that tone started to rustle and volume also have some issues with fluency of go. So I’d like to change them but official music-man shop doesn’t ship to my country. So only close (push/push a500/a25k and 10mm shaft) that I found is china Parts. What do you think is it rational substitution or better to try to find originals that also doesn’t look like high-quality. Did anybody have changed pots on majesty? I mean namely push/push not pulls.
And also is it a good idea to change output jack to switchcraft? I’ve no issues with original but on one of my previous guitars Schecter km6 mkII it have had a noticeable effect on sound.
