Momo wheel center bore

Momo wheel center bore
Years ago I installed a modern 350mm Momo Prototipo in my car. Although I liked it, it was sanitary and I decided I wanted something vintage with a bit of character. I stumbled across a 30 year old 370mm Momo GT and snagged it. It's a Euro market only wheel with red stitching, and in surprisingly nice shape for its age.
After cleaning it up and treating the leather, I went to install it to find it doesn't fit. The center bore of my Prototipo is 55mm, whereas this GT is 51mm. As a result, the wheel doesn't fit over the lip on the horn button retaining ring.
Has anyone run into this issue and if so what did you do? It looks like all the horn retaining rings available are for a 55mm bore. Same goes for the horn button, if I find a smaller retaining ring I'll need a smaller horn button to fit it.
My other option is to open the bore up in the wheel but I'd rather attempt to find the right parts.
Thanks
