Drivers Door mechanism help

Hi All,



Today decided to replace standard 6 speaker for hifi speakers, changed all speakers tweeter will do later amp and subs later.



My problem, in my lack of experience i damaged the internal door open mechanism, the white push fit connector slips under a black clip before being pushed down.



this black clip is damaged, what do i need, to replace this? or am i better off just epoxy this? (epoxy sounds like a bodge though and id rather not)



thanks for looking
