Does anyone have any experience using Buff modifiers on Speedotron Heads? Specifically 102 heads?

I have both Einstein 640's and Blackline 102 heads, and seeing how I have had the Einsteins for much longer I have far more modifiers for that system. If I can, I would like to be able to use the same modifiers on my 102's, but so far have had no luck finding any adapters specifically made to do the trick, and after searches here and on the net in general I have only come up with one discussion about how to DIY it that was neither clear or convincing that it actually worked. I was wondering if anyone here has either DIY'd something that worked well or has any idea where I can buy adapters that would work.

Thanks.
