Tomfoolery

I have a pair of Heresy I's that I purchased used. I want to make some riser stands that look and work like the ones that come with new heresy's. Can someone out there who has these risers on there heresy's give me the basic dimensions? I need to know front & rear height, as well as the outside width and depth. Also, how are they constructed (thickness of the wood, etc.)? Do the stands attach, and are there any other characteristics that aren't apparent in the photos on the website? Thanks in advance for your help! Tom
