The information is out there, you just need to do a little searching to find it!
Here's a link -
http://www.ihra.com/component/k2/itemlist/category/208
The way the listings have been updated makes locating the right entry harder, but not impossible. If you use a "find" command in your web-browser (Firefox uses Ctrl+F) you'll be able to locate the most recent updates from the list, instead of having to scroll the entire document.
Of course, as mentioned previously, a call or e-mail to the IHRA might also be a good idea!
Best of luck with your new project!
