Fitting new radio

[Razorman]

My old radio was not working and so just purchased a new Pioneer one that I can connect to via Bluetooth and can charge my phone via an onboard usb socket.
All good so far but I’m having great difficulty fitting the cage to hold it.
The cage is a standard size, but I have a metal dash and the hole in it for the radio is 5 or 6 millimetres bigger than the cage and there is no thickness behind to enable me to bend the tabs on the cage to securely fix it.
Has anyone else had this problem and know how to solve it.

Just too wide or too wide and too tall?

Think I'd try Aralditing some pieces of metal behind (fed in from the front) to close the gap down a bit

I fitted a replacement head unit in mine a couple of years ago, and the cage hole is a lot bigger than the cage.
I had to pack it out, and then just bend the tabs to grab the cavity as best I could.
I got it secure enough, but it wasn’t a perfect fit.

The opening is a few millimetres too tall and as I said 5 or 6 mm too wide. The new case has a small lip on it all around, which should stop it going through the opening, but it will just go straight through.

You can buy fascia trims that may help but you may be tight on the bendy tabs actually reaching anything.

The bendy tabs will stop it falling out, but they can’t stop it falling in as the opening is too big.
That’s the big problem 🤔

The permanent fix would be to remove the dashboard piece and bond a sheet of aluminium to the back, with the correct size hole cut into it.

Bit of a faff but should be reliable?
