I have upgraded the guides on my SCM MM16 with the Carter's some some ago.
These were the first version and a bit fiddly to adjust, required allen keys. Far better than the original Euro guides which many love, but I never could get the hang of them.
Easy to set up for my 1" blade, plenty of meat behind the teeth to get the bearings riding smooth.
Still hate ever changing blades (reason I bought my 14" PM).
