Hello there,
I think you may need to get another uf4007 diode.
Having said that you could take a couple of trimmed diode leads and twist them around the stubs on that diode and solder them.
If you do not feel confident doing this, diodes of this type are cheap.
or Perhaps give Bottlehead a call and I'm sure they can hook you up.
Best wishes for the Holidays.
