If you stretch the typo possibility all the way to M78, instead of 70, you can get an answer of "similar". The Model 78 Sportsman was a 'budget' 700 ADL.
So 78 Sportsman and 700 ADL stocks for the same action length will interchange. ...Not that most people would want to do such to a 700, though. The 78 Sportsman stocks were extremely plain and straight-grained; so much so that most look like shaped 2x4s.
The 78 Sportsman stocks will also interchange with 700 BDLs and CDLs, but magazine parts may need to be added or subtracted, depending upon which way you're going with the swap.
