I spoke to VW Heritage yesterday about the Cam with the undersize gear, they told me they took what VW supplied in good faith but had heard there may have been some -2 in there which is what I have.
They said it's OK to fit but it just means the tappets will be a bit noisier...errr no thanks it's out of spec, they offered a refund, err..no thanks there are no more cams.
They told me they checked and there are no more VW DG cams available but I'm not sure, I asked them to check all part numbers because I looked up all the gear sizes and there are 11 of which classic list 9 so perhaps there is some stock of unusual size gears, perhaps wishful thinking.
If there are no more then hopefully somebody will start making reproductions, not aware of any myself?
Numbers are
025109015C -3
025109017C -2
025109019C -1 ( not listed)
025109021C 0 ( not listed)
025109023 +1
025109025 +2
025109027 +3
025109029 +4
025109031 +5
025109033 +6
025109035 +7
So rolled up my sleeves and drilled out the rivets from my old cam and my new cam, then punched them out. Cam was wrapped in a rag so that it didn't get scratched.
I also was thinking of having a go at riveting my self so ordered some rivets, flat head are hard to find so ordered round head solid steel rivets 6mmx20mm
The rivet is 14mm long when fitted so I will have to cut down, it's 13mm long finished with an 7mm diameter x 2mm formed head so I will make some punch tools and test this.
