MS 881 .404 to 3/8 Sprocket Nose Part Numbers

[Mad3400]

I've picked up a MS 881 with a Stihl 41", .404 bar and looking to swap the .404 sprocket nose with a 3/8.

After some digging I was able to find 4 different sets of part numbers below (as well as the Stihl 41" bar information).

Is there someone who can confirm, which ones will work as a "Bolt On" application?



Stock Stihl 41" bar 3002-000-9757, .404, .063, 12 Tooth (Nose Sprocket), 123 DL



3003-650-2539, 3/8, .063, 13 Tooth

3002-650-2526, 3/8, .063, 10 Tooth

3003-650-2528, 3/8, .063, 13 Tooth

3003-650-2551, 3/8, .063, 11 Tooth




Thanks,

It will have to be a 3002 mount

I get that, but supposably, these worked for the 880's back when, never got confirmation.
