Engine out can I install Dougs beforehand

Installing engine with 904 trans with manual steering.Dropping the K member is not a option for me right now.Dropping it in Friday morning.Here is the plan pull back the t bars and remove the center link.Take the motor mounts off the engine.Wire up the drivers side header to the shock.Then drop in the engine a few inches short of where it needs to be.Bolt the tranny to the tranny cross member. Then bolt up the drivers side header.Push the motor over to the drivers side as far as I can.Next drop in the passenger header and bolt it up. Does this sound like a good plan or am I missing something?
