I have a new MXZX 1.250 track ,there is only 1 inch of clearance between track and heat exchanger.....There will be 3/4 ..5/8 after i put the picks in.....Will the tunnel protectors stop the picks from hitting exchanger.... w00t

yes

You need to install new (thicker) tunnel protectors, the stock ones will not protect the heat exchangers. Your doo dealer's parts department can get you the correct ones.
