Don't see a model # If it is a sealed type burner Viking had issues especially with the 6 burner units. They finally resolved issue with new burner bases which have a lower resistance through the electrode.
If it is an open burner Samurai is spot on.
You can call All Viking Parts manufactures only parts distributor give them model number and serial number and they can give you proper burner base #'s They can be a challenge to remove sometimes. Verify that is what you have before we get into that.
I was going to attach a photo of the different burners from their website so you could see the difference, but the fine jerks at Viking don't allow that their photos are copyrighted
