Yep, only have the grill element in. I've tried literally everywhere I know of. There's a shop up the road called 4YourHome and if they don't have it nobody will. I'm having an ongoing convo with the eBay seller to see if there's anything more suitable but looks like it may be a case of biting the bullet and getting the £50 original part.
For those interested, here's some photos showing the original element and the spare I was sent.
