You won't find part numbers for the screen and interior because Scalextric didn't sell them as spare parts but there are sellers on Ebay who strip down older cars and sell off the parts and they are your best hope for an interior and screen.

It is likely that it will be way more expensive to buy secondhand parts than it is to find a rough complete car on Ebay and strip off the parts that you need .
