Since another member gave me the red X, I think I need to reword my answer. What I mean by doesnt matter by them being spool mounts in my picture, is I wanted the member having issues to look at just the part of the mount in the picture where it attaches to the engine block. Weather you are using 73-76 spool mounts or the earlier 67-72 mounts for your specific application, the LH rear mounting ear on a 340, 360 is moved forward compared to a 273/318. The 273/318 mounts will bolt up and require just a longer bolt for that one mount ear, and a spacer or stack of washers.
