Possible Spyder Seat Belt Conversion

[jebracing]

Does anyone recognize this bracket ? I purchased an Elan seatbelt kit maybe ten years ago (or more) from eBay. I had thought it was a spyder conversion. I pulled this kit out to install it on my S3 coupe today but it doesn’t match what I’ve seen here on the forums, being considerably shorter and without the top bolt hole for the belt guide. Any ideas?
Thanks.

I think the Coupe and DHC versions are different. You might have the DHC version
