check out the few wreckers in Surrey on scott road near the big Lordco that's close to the pattullo bridge.
Ken's Japanese Used Auto Parts
Ken's Auto Recylers
They might have something, it might be worth a shot.
Also check craigslist, I search for Preludes on there all the time and I've seen a few part outs here and there.
There's also a place in Port Coquitlam, J1 Autowrecker, I see them advertising with Prelude parts so you might get lucky there.
If you paint with spray cans, please post the results. I'm interested to see how it came out.
Good luck!
