Just did this yesterday to my car in fact!

Malsal's right.  You flip the felt end for end, depending on right or left hand drive.

I test fitted on the firewall first to make sure, then put it on the carpet to cut out the right areas.  Think three times before cutting, to make sure you're cutting correctly for your drive side.

Then, after cutting the carpet, I glued the felt to the carpet, and let dry.  

Before gluing the felt/carpet into the car, I glued a few squares of sound damping mat on the firewall - nothing scientific or over the top, just some weight to reduce drumming, as I'll not have easy access to do this once the carpet's in place.

It is tight getting things in behind the gas pedal lever, but with some patience, it will all work out.

Thanks all.  I think I got now.

That cut out on the lower left is there for a rhd accelerator pedal.

The pieces in the picture are the backing/pad for the interior bulkhead sitting on top of the carpet that is to be trimmed like the pad to fit with the pad around the pedals and onto the passenger bulkhead area.  I'm sure I'm just over-thinking this and the stupid thing just slides right into place.

Is it the piece in the picture we're talking about???... (I can only see one piece of carpet..)

IMHO its laying on its face.  They usually trim the underfelt to fit around stuff leaving you to tailor the thinner "face" carpet to give a neat fit.  

To me that piece looks like the trim used to cover the engine side of the upper bulkhead on early cars (Mk I/IIs) ..but maybe somehow modified for  a later car???  The large hole in the top centre (as you look at the photo) would be the firewall hole behind the centre instrument pod.  But the more I look at it the less I can see how it would actually fit...  

It looks strangely familiar .. but wrong???

I believe the top of the pad butts up to the bottom of the tray which the binnacle sits on.

It isn't your brain... confusing to me too.

Look at the floor/footwell carpet pad first. How far up toward the pedals would it go? if this is the bulkhead panel, and it is upside down, it looks as if it is big enough to go up in behind the instrument cluster etc. There might not be a cut-put for the binnacle because it may be made to fit central or offset instruments, in which case you would cut to suit. The two small U-shaped cut-outs appear to be in the right place for the demister tubes, the central rectangular cutout for the heater and the remaining one for the pedal box. Maybe the whole panel is supposed to be cut horizontally, so one part goes above the parcel shelf and the other below.

But that's a guess!

Its a pain -but in many cases the supplied carpet is too big-- you will be cutting it down.

it will take a few vertical slits to fit up behind the heater box. then i usualy chop out 3 inches between those slits for less matearial to have to cram behind the heater.

Working behind the pedals is also tough - ( knotch around the pedal box ) and have flap coming down over the acceleator pedal .   simple slits aloow the gas pedal to extend thru the carpet too.

The bulkhead carpet lays in then typically the floor carpet comes up on top.

I bought a new carpet set and I'm not sure how the bulkhead piece fits around the pedals.  The carpet set came with a backing/pad that supposedly fits in place on the upper bulkhead and the company suggests that it be used as a guide for cutting the carpet piece that attaches there. But I'm too stupid to figure out exactly how that pad fits and I don't want to hack up the bulkhead carpet itself 'till I know for sure how the pad is supposed to fit.

If someone could supply a photo of their carpet as it goes around the pedals it would be very helpful.

My car is an '84 salon, left hand drive.  So what is the orientation of this pad when it is installed?  Does it go exactly as shown in the picture with the cut-outs behind the pedals and the large uncut section in front of the passenger seat.  Or it is up side down in the photo.  Or what?  

I've stuck it up behind the pedals at least a dozen time and my pea brain just can figure out which way is up
