Richard.
On my Jan 1968 +2.
I used the originals as templates and made new ones.
Used a type of fibre board 3mm thk and 5mm thk foam.
The crease in the vinyl disappeared after approx 3 months.
The “L” shaped brkt is screwed to back of dash and the heater valance passes at the back of it.
A screw and cup secure the opposite side, the screw just long enough to pass through the carpet and into the body.
You will notice that I am still missing the heater deflectors, which I still need to obtain. The deflectors should either pass through the slot in the valance or be very close to it.
my 68 +2 is also an ally plate riveted to the dash bracket. guessing they ran short at the factory. My side panels, possibly not original, do not have the holes shown. I think they are left with a gap at the lower edge to allow warm air to circulate… currently not fitted.
According to the parts list available in the wiki the deflector moulding was fitted from chassis 1170 , so a 68 car may well have been built too early to have had it fitted from the factory.

I’ve just visited the “Wiki-coming soon” re both the Heater Valance and Heater Deflector and interestingly it confirms Brain and wotsisname comments. This is good to know.
So as my car is 0173, well before 1170, it would not have the Deflectors fitted.
Regarding functionality the slots do allow the Hot / Cold air to pass through, so I am guessing that a PO made the change to improve the Heating / Ventilation.
A mini project for the coming months is for me to make the Deflectors, which should improve the air flow even more.
That’s good to know the allow plate is correct. I think my dash was original before I replaced it, so i assumed it would have been. Back to the trim, mine had small bocks of wood attached to the inside to creat/support a curvature in the trim panel to allow the heater air to vent.
I plan something similar. I put a plate with a captive nut on the lower dash fitting and have extended and bent it to give another potential attachment point for the side trim.
