B&C Tweeter Help Needed

I need to replace the tweeter in my Berg Ht112 cabinet. The B&C D32 model tweeter was apparently discontinued and replaced with the B&C D35, which is a neodymium mag tweeter. The specs seem similar but the D35 is slightly smaller. Any help here would be really appreciated...

1. Would the diaphragm from the D35 fit the D32?
2. Anyone compare the D32 vs. D35? Do they sound the same?
3. Is it worth me trying to track down a replacement diaphragm for the D32 or should I just replace it with the newer model?

Thanks in advance!

 

Sorry - just edited my post for clarity... (blown tweeter, need to replace or try to fix).

 

Pretty sure the diaphragm is shot. Bergantino has them listed on their site. But $50 + $25 shipping is a little steep for just a diaphragm
