Necks on a II
Allo ,I remember last winter switching and did put a Serie III neck on the Serie II,and did the oposite!It will fit,,and I did prefer the III neck on the II Serie specialy in opening up the sound and it was easier to play overhaul coompare to the original II neck! Also the arch on the Serie II is higher then the Serie III is lower,which I do prefer!
Hope this help!
All the best
