Leven/TVRCC is same thing I think. Mine were £55 in 1997. They look great but I found the lip didn't fit the curvature of the GRP too well and the edges are sharp. Also, they scratch easily so try not to scuff them! They ceratinly won't come off if you stick them down propoerly.
True, thinking back they were the same, think I may have ordered mine through TVRCC, d'oh. Got a memory like a sieve that's rusted so badly the holes have all joined.

I’ve got the Leven (Griff 500) one’s, they are self adhesive and look brill.
You do have to make sure they are positioned correctly so the lips are snug to the sill and the ends don’t ride up the curve, but that wasn’t difficult to do.
