Does anyone know where you can get good levers for a lyre

TLDR: is there a place that sells small harp levers so I can put them on my lyre myself?

Maybe wrong flair but it’ll do, so I recently bought a lyre and love it ( got it over the harp due to price, probability, and its just cute. ) however, I’ve found it to be a massive pain to constantly retune the lyre just to play a piece with one or two sharps/flats then having to tune it again just to get it back to naturals. And I just really can’t play a song with accidentals in it.

My question is, is there a place that sells small enough harp levers so I could attach them myself? I know there is a company that sells lyres with levers on it but they are so expensive that I might just be better off getting the harp instead.

I found a place that sells universal harp levers for $14 but 1. It gets hella expensive ( $224 for 16 and time gonna be upgrading my 16 string lyre to a 24 string ) 2. I worry that they might be too big for the lyre ( mainly for the 24 string ) 3. Worried about it damaging the lyre ( I have a Donner lyre and while they are good quality I still worry.

Just looks for advice
