Im new here and in the middle of dropping in my 6.0 with a th400 in my 87 cutlass. I have the engine and transmission in the car but for some reason the motor mounts will not meet. I have the trans dapt 4595 set back plates and trans dapt 4233 solid motor mounts. Im using the truck pan as well. The pan is sitting on the crossmember and the driver side is lined up but the passenger side is not lined up at all. What mounts do i need or do i need to hammer on the transmission tunnel any help will help. I have a set of clam shell mounts but they look like they wont fit the set back plates the clam shells look to wide.
