Ordered HD3870 will my mcw60 work?

Well I ordered the new HD3870 card and it should be here in a week. I'm just wondering if anyone knows if my current mcw60 will work on it. Right know I have it on a x1900 A-I-W card, but I have a feeling the hole pattern changed between now and then. I tried searching on google and here and couldn't find anything. If someone could help me out I'd much appreciate it. I want to be able to put my card under water when I get it, to see what it can really do.

thanks, -rob

Did you check swifty's site for info? You might have to get a custom mount plate, but not 100% sure.
