Hi
I fitted Sarken plates to Dartwins. As Gaz said, the rear section is the same so fits perfectly. The front section needs some modification, but with some decent cable ties (that can withstand cold temps) and a bit of trimming you can get a reasonably good fit. I used my Dartwins with modified Sarken plates for a couple of seasons both in Scottish slush and warming afternoon Alpine snow and they worked well.
