Motor Mount modifications for 340/360 into Early A

If I visualize the pictures in the link above correctly am I seeing two ears with two holes each on the passenger side of the 273 block? And, the mount bolts to the two rear holes and one front hole?

I was always under the belief that 273/318/340/360 blocks all had the same two front one rear hole arrangement on the passenger side. The drivers side has the same arrangement but the spacing front to back of the ears on the 340/360 is narrower than the 273/318.
