Yamaha 12 dovetail ?

[Len Biglin]

Hi everyone , I have a Yamaha L112-8 on the bench which is a slotted head 12 string , it is in dire need of a reset , before I start however , does anyone know if these have a dovetail or dowels , and what about AMG ? The lacquer is thicker than a martin but not over the top thick , and Ive cut around the heel easy enough .Thanks Len
