Can someone please help

On a tech 1 , what should the engine under tray be like ? And fit with the air duct tubes from the kit

I've got the correct air ducts, and also the splash guards on the bottom corners of the kit, I've also got an under tray here that looks like it will fit, but has no holes cut in for the air ducts ? This was not originally on the car

Should the correct under tray come right up to seal the while corner off, and have the holes in for the ducts ? I've also seen a flat pre facelift under tray without those sections that go up sealing it, or would that be the correct one with an extra little square section for each side with a hole for the ducts ?

Would be a big help if anyone can shed any light

Or - should I just attempt to cut holes in the one I have ?

Cheers

Tech 1 undertrays have the holes for air ducts I have a couple at work, normal chromie undertray would be without holes otherwise both are the same.

Mine are in three pieces the undertray is attached on both ends with a roughly squareish piece with the holes for the ducts in them. These screw to the undertray and the plastic inner wheel arches and also the side of the front valance.

Thanks guys , so there are 2 types ? , any chance of some pics ? Or one on the car if you could take a pic pointing in from the front tyre at that inner corner area ?

I'm wondering if I can just cut out the holes in mine , but then I have no idea if it will work like that or if it will be easy or hard to do, as once the tray is put in place you can't see behind, I'm thinking maybe try chalk or paint around the end edge of the air duct and put the tray in place and see if it touches and leaves the imprint on it, where to cut ?

But ideally I'd like to find the proper one to buy , if anyone had one for sale feel free to let me know

I won't have any pictures for a couple of days but the top 3 items on the image below are what I have, which is then screwed onto the undertray. Obviously the first two are the air ducts which you already have. Funnily enough I haven't been able to find the undertray yet on the realoem site .
