When is a new Clutch release bearing flange needed?

Hi forum! I’m installing the Hill Engineering Clutch Release Bearing when I do my new clutch service in the coming weeks on my F1 360.
Should I also install the Hill Engineering's Clutch release bearing flange when I do this service?
Is it a must or can I get away with reusing the original bearing flange that the car came with?

Your advice will be much appreciated!

 

Unless you have had a release bearing failure which has damaged the flange I would go with the original. My 430 has been fitted with a hills bearing after the oem seals failed, using the oem flange. Be sure you get the correct bearing as manual or f1 and different pt nos
