IDK but I have the paperwork scanned, I just can't figure out how to find it and post it. I may hav to send it in an email to someone here at FABO and them post it for us.
And I got to thinking about it (and this is where trouble starts) I have some info on the R blocks as well. If you guys want to post that up, I'll see if I can find it and we can post that up too.
