I did not cut my mount off, but it was a weld in, i used a hoist to drop the motor in without the tranny, got the drivers side and rear mount in and then lifted the tranny up and on the motor while the hoist was still holding it, and if you line the axle holes and hubs up properly, the tranny mount should be forward of the OE mount, but i dont know how the hasport mounts line it all up. And for the front mount, you will not need it at all, the three other stiffer mounts do a good job holding it just fine.
