Where to Buy Mid-Glide Fender Spacers

Hi Everyone,
Doing a mid-glide swap on my ride.
I need to know where I can buy some good looking fender spacers like you see on the wide-glide set-ups. They don't need to be chrome, since I will be powder-coating of epoxying them gloss black.

I need 3/4" thick ones that have the correct bolt spacing for a Sportster. I can find big twin sized ones all over the place.

Any ideas?

Thanks ahead of time,
Dan
