engine swap question

I just finished removing the tired old 273/2bl from my 67 cuda and installed a 69 block 318/4bl.

Question is, in order to get the 318 lined up correctly and leveled, i had to use a taller motor mount on the passenger side.

The 904 trans went into the crossmember just fine.

Has anyone ran into this issue? The car is an original 273/2bl.
