Has anyone got a spare heat shield? The one which protects the heater fan.

Is it 160151 in the picture? Mine is missing and was going to wrap foil around the exhaust.

You might want to look at my resto thread as I made one using some original parts and some less asbestosy material.

I made my replacement out of sheet aluminium backed with special aluminium heat shielding. The original backing material looks suspiciously like some type of asbestos and mine was falling apart so took the opportunity to make a new one. I'm pleased with the result, you can see how I did it about half way down the page.

Several folk have suggested refitting this with screws or bolts (rivnuts, tapping bolts?) rather than the original pop rivets, to facilitate in-car downpipe removal. Sounds like a good plan to me, anything that makes this swine of a job easier is great!

When I drilled out the rivets that hold it to the bulkhead, the steel strap across the back failed and sheared off; easily repaired so long as you don't mind the effort...

I lost my original during my restoration and fashioned a likely looking alternative out of a piece of stainless sheet which I just happened to have lying around. It is probably a little larger than the original but I don’t think that is any disadvantage.

I have done as Steve has suggested and used a couple of screws with washers and nuts behind the plate itself in order to make it stand off from the bulkhead matting. The bolts are then passed through the bulkhead and additional nuts are used behind the carpets to hold it in place. I have reasoned that there is sufficient air passing behind the shield to limit the transfer of heat across into the matting.

On the only occasion when I have removed the downpipe from the engine whilst it was in the car, it was very easy to undo the nuts behind the carpet, drop the heat shield out of place and then undo the downpipe which dropped off the exhaust manifold without any drama at all.
