You'll probably find those inserts will be moulded into the seat with large spreader plates below the CF

I'm struggling to get a good mould from a race seat that i have, and I'm hoping you can give me some advice and help.

This race seat is an infuse carbon part, but it has some metal insert on booth sides, to fix it to the car, making it impossible to make a "direct" mould of it.
I believe that this metal parts are glued with some epoxy glue, so it's literally impossible to remove them.

The metal plates have around 2 ~ 2,5mm thickness and the "bolt" has around 4,5 mm.
As you can see from the pictures below, this metal parts create some undercuts and i'm not sure how can i overcome them.

The "bended" effect of the seat surroundings makes is harder to solve it.


Any help will be appreciated 

Here's some photos so you see what i'm talking about.
