Trim parts in the USA makes these brand new, I think National Parts Depot has them for around $120 usd for all 3 pieces. I have an original but hadn't looked at it for years and it is pretty dry and brittle. And as you have to push this into place around the rear window I think new (and nice and flexible) would be the ticket. Steve.

They have the front piece as well for about $40 usd. (they both are black plastic and you paint them to match your interior)

I am looking for the same trim, looks like RPM in Saskatoon has the front trim for $19.95 and rear 3 piece for $99.00. Black only. Any tips on painting these? Assuming it has to be somewhat flexible.

SEM makes really good interior paint comes in a spray can, if you order from RPM ask if he has them in stock sometimes he has to order from factory and may take some time to get. i just ordered a set from muscle factory in California and they had them in stock

also make sure to get a shipping quote as the front piece is fairly long

Already placed an order with RPM, thanks for the info on the paint. It is available on Amazon.
