C pillar interior trim piece for 1965 Valiant Wagon

I'm not sure what the pegs are . . .but I only have 1 broken piece to show. Are we talking about the same part? Here are pics of the partial that I have. Front and back. Mine screws on with well, at least 3 screws, maybe more, you can see where the holes are on my piece but its broken and the other broken off part didn't come with car. The driver side is completely missing.
