Might anyone know if there are any "illusion step" plans out there?

The short ones - Like those used with "the Lion's Bride".

I have yet to try Illusion Systems. And I was hoping that there might be a set of plans published in a book. I thought Tarbell might have had them, but I am away from my library and can't check.

Any assistance, even just dimensions will help, as I am building these for a TV gig that shoots next week.

Any help would be greatly appreciated.


Thanks.
