Theres a bit of info regarding this on mazda247
Crazy canadians where the first to do it IIRC. Theres not alot of info available and what there is, has been translated from french.
EDIT: There seems to be alot more there then what i found on mazdas247.
EDIT2: WOOT looks like if i was able to grab a capella front cut would slot pretty much straight in.
