Brake Drum Cover dust seal

I have a ’97 TRX300FW 4×4… I’m currently replacing bearing and seal(s) on the rear brake back panel/plate… Parts are ordered (haven’t arrived yet). Everything is going fine, I got axle out, I got bearing and seal pressed out of back panel/plate and everything.

However I can’t figure out how remove the dust seal from the brake drum cover!!! lol I done tore it all up, and now thinking I should punch it out via the 4 holes on the inside cover. I’ve tapped on it a bit, but thought I’d ask before I damage the cover… So what’s the trick to remove this dust seal on the rear brake drum cover? lol tia

joined just to ask this question! ha
