K Frames - A vs B/E

HemiDenny - Thank you. Not sure I was looking to put an B/E K in a A body. I have an A body /6 (67-72) K I wan to do a Gen III swap with. Schumcker mounts are on back order. I have a new B/E QA1 K and was curious if it would fit - which it sounds will not: So - Sell the QA1? Wait for Schumaker? Trade?
