got some new drums /shoes on order as the handbrake isnt up to much these days

i see that i must swap over the old abs rings , is there any tips on how to do this or is it obvious once apart ? just asking in advance rather than getting stuck when its all apart

 

I just used a lever bar matey and levered against the edge of the drum with the other end under the ring. There is also a metal ring underneath the abs ring.
