Headlight of the Roctane for the R18 (Classic)

I just recently saw this R18 in Facebook. Has anybody transferred the headlight of the Roctane to a R18 (Classic) already and can tell me the part numbers needed? Obviously I would try to reuse as much of the parts which are on the R18 already (e.g. I was told that the speedometer should fit into the headlight of the Roctane).

I'm looking to do this same mod. Hopefully, all we'll need is the bucket.
