Need help on 340 motor mounts

here are the 318 mounts i modified.
I welded the top ear on that bolts to rear 340/360 boss and rather than cut a section out and re-weld it to fit i added 2 thick washers.Hard to see but the mount is black and the grey area is actually 2 washers.
Mine is offset back somewhat like yours as well
