Midshafts question

[Soljr]

'm pretty sure the SN and RN midshafts are the same length from back of the bearing to the front of the coupler but I want to make sure.

The only difference is the size of the main bearing housing right???

Correct. Same length. The thread size for the coupler on the SN is smaller. You can replace a SN Shaft with a RN one, you will just need a coupler to match the shaft.

650 SN Skis had the smaller housing. 61x 701 SN Skis have the larger housing, same as RN Skis.
