have been lucky enough to get my hands on one of the Ltd edition rumble frames with one slight problem the dropouts are missing
Cool find they're great bikes. Did you get it second hand or new, although if it was new you should probably have got the dropouts too??
Anyways the best I can do is get mine and scan them in and that way perhaps you can make some. I'll put the files on the facebook group and you can download them and cut them out. https://www.facebook.com/groups/mcfanclub
The only problem i can forsee will be threading the derailleur dropout hole. Although you could go to your local hardware store and get a m10 x 1.0 tap and do it. Just depends how handy you are with saws files etc.
Might not be pretty (depending on your skills) but it will work...
