Hello All,
I'm working on cleaning and prepping the Orange Ones underside. The rear trunk is in good shape, a few typical rusty spots but very minor. I want to POR inside and out on the trunk but really can't do a thorough job with the heat shield in the way. The car will have a six some day. If I remove it permanently will my future muffler bake the back end of the car? Advice appreciated. Attached image(s) |

I removed it for my V8 and have a single 2in/2out muffler in that location. No heat problems for me.

Advice appreciated. Just drill out the spotwelds. That way, you can put it back on at a later date if you want ... The /6 cars (And presumably some really early /4 cars) have the heat shield screwed in, not welded. (IMG:style_emoticons/default/shades.gif) Andy |

Thats true... the Great Pumpkin's heat shield is held in with sheet metal screws. We took it out and it made cleaning and repainting everything much better.
They should have all been done that way. Oh, and yeah we are putting it back in. But we are painting it with header paint first. |

This shield would have been much efficient if it was made with shiny metal.
At this place you are fighting against heat radiation. If you want a lighter car replace this part with a thin polished aluminium shield. . |

My red 72 hasn't had on since I bought it in '99. I've never noticed a problem (with the exception of melted chocolate bars (IMG:style_emoticons/default/biggrin.gif) ).

Yeah, I pulled mine off in accordance with my weight fetish. It's made me contemplate getting a job as a pizza delivery driver, but never gets hot enough to harm anything. Of course, people don't like pizzas that have all the ingredients on one side, so I should probably scratch that idea. |

It looks like I'll drill out the spotwelds and attach later with screws.
Thanks everyone. (IMG:style_emoticons/default/welcome.png) |

It looks like if you use screws on the floor bottom they will protrude into the trunk. You might want to plan ahead and put bolts or button head screws there.

(IMG:style_emoticons/default/agree.gif) After dicking around with the spotwelds for multiple hours I got out the ultimate solution. (IMG:style_emoticons/default/sawzall-smiley.gif) No chocolate bars in the trunk for me. I'll take my chances with the heat vs drilling holes through the trunk. Attached image(s) |
