a904 front seal removal

Well I thought this was going to go smooth...but its been 30years since I've done one.
Tried walking screwdriver around lip with no luck before knocking the seal in on an angle and decided to stop.
Tell me the next step. I heard insert screw on good side and pry out with clawhammer or
just whack straight in btwn seal and case to bend lip all the way in.View attachment 1715061057
I just did this a couple of months ago. Bought a cheap AutoZone seal puller and kept the flat part of handle against the input shaft, put the hook part under the inside lip and lever it right out.
