I need to replace the flyback transformer on my Atari SC1224 CRT monitor. The flyback I removed from this monitor has a model number of Kf4825G, and has an RC snubber attached to it, which does not seem to be easily removable. The high voltage cable goes through this to the CRT. Here is a picture of the bad flyback: 
The only replacement flyback I've found, which according to the eBay listing it's a replacement Kf4825G flybacks, does not come with the RC snubber. This is the eBay listing for it. And here's a picture of it: 
Is it possible that with this replacement flyback, the RC snubber is not needed?
Or, should I attach the existing RC snubber to the new flyback? It does not seem to be easily disconnected from the flyback. Looks like I would have to cut the thick red HV cable? (I don't think that's a good idea)
I already messaged the seller asking this, but he has no idea.
Here is the Service Manual, if anybody wants to see it.
Thanks for your help.

You are probably going to need a snubber to prevent the ringing from damaging the transistor driving the transformer. If you have access to the transistor then you can measure the ringing and determine whether or not it exceeds the rated voltage but this might damage the transistor in the process.
