Al, you must be one of the original buyers of that kit. I started to make the Wilwood adapter back in 1999 so it has been just a little over 10 years.

I recently designed a kit that uses radial mount Wilwood calipers. These calipers have weather seals on the pistons and the radial mounting is more rigid than the ear mounts. But the radial mount calipers are a lot more expensive than the older ear mounts so this new kit hasn't been very popular. It is what I'd use on my car if I was going this way, but the price point seems to keep people from buying it.
