Very good advice. If you're still game, a set of trim tools and replacement clips of all sorts are usually available from your favourite large online retailer.

Very good advice. If you're still game, a set of trim tools and replacement clips of all sorts are usually available from your favourite large online retailer. I recently bought a set of trim tools for $AU28 and am assortment of trim clips and roof liner clips for a few more tens of dollars. Definitely worth watching a couple how to videos on YouTube too. Having said that: don't be surprised when you break something.
