Blocking the Firewall Heater Tube

Been trying to find an easy way to block the firewall heater tube on the engine side during the summer. Had a tin foil cap with hose clamp that worked but looked pretty bad. Did an internet search and found nickel plated (shiny) steel 2" metal snap-in panel plugs from la.sales@mcmaster.com for $7.95 for 10 pieces. They look great when inserted in the tube. You need to have 1/2" or so space between your heater and and the tube to get it in place. Thundered down the highway at 50 mph and it stayed in place just fine.
 
Use the plastic endcap from a grease tube. They fit perfectly without the need of any clamps.
 
Hi Oldgaerz

do you have a picture, please?


btw: I stuff a knob of "butter bread" aluminum foil in the front of the entry hole.
