Any chance you had any part numbers laying around? I thought you posted them but perhaps it was someone else - couldn’t find them either way. If not no big deal I can certainly dig them up nothing I haven’t done before 
There are specific orings for those hard lines also
Edit: I see you have them there, nmv
So 4 o-rings for the cooler and another 4 for the hard lines? That’s it? Any reason I need those bolts - are they torque-to-yield?
The torque is pretty low, so I’d be very surprised if they were TTY.
