Looking to mount my oil cooler in front of the radiator using the suggested trick with the automotive radiator zip-ties.

Should I be using any padding between the two (cooler and radiator) and at each end of the zip-ties on the tabs? If so, what kind of padding?

Also, what is the best route for the zip-ties to go through each?
Being that the radiator's chambers are walled with some very thin metal, I don't want to start popping leaks with some vibration!

Images/ideas appreciated.
Thanks
