Hangar Flying

I've searched around google and what not, but was unable to find a solid lead on a supplier for Long-EZ wheel pants.  I've heard of the solid core forms or patterns being passed around as well.

Whose design is considered the best, and where can I get the completed set or pattern?

My current set are hard to take on/off and are cracked. I suppose I could use them to make a mold though, any thoughts on this route?

thanks in advance.
