Bulkhead heat shield / Nimbus

[Bmac]

I want to replace the bulkhead heatshield in the 172 as its falling apart.

I see that I have 2 options:
1) Replace with nimbus
2) replace it with a heat shield from a 1.2

The problem I have is a can't find where to buy the 1.2 shield from, and I can't find any pictures of the nimbus fitted so I'm unsure of what size it should be and exactly where it should go.

Does anyone know where I can buy a 1.2 heat shield from or have pictures of the nimbus in place so I know what to do with it?

It's an old picture and not very detailed, but this is how I fitted a sheet of Nimbus in my circuit car.

I just removed the header tank bottle from the bulkhead, then added some heat tape to the left and right of it. Used self-tapping screws to secure it along with washers.

It was just a sheet of 300 x 600 mm from Merlin Motorsport. Link - https://www.merlinmotorsport.co.uk/p/nimbus-gii-2-layer-heat-shield-material-aero-nim-s

Lasted forever, zero issues, in it's fact still on the car 7 years later racing in 750MC championships.

Great, thanks for that. No issues with putting it in with the engine in place then?

Not the best pic but I’ve got a huge chunk of it on the bulkhead. Theres a few original screws holding various bits onto the bulkhead/scuttle that you can poke through to mount it with

Nope pretty straight forward. I may have removed the inlet. It was a long time ago.
