Does anyone know where I can get inner sills from? Cant seem to find any.. or is there a inner sill from another car a close match?

TIA

At the moment even the pattern parts places only seem to have the outer sills.

Here is one of the places I was looking at: https://www.carbodypanels4u.co.uk/va...-mk1?limit=all
