my newest acquisition ( 76 nova ) needs rear tail lights buckets.

Problem is the cheapest I have found them is on evilbay for about $50 ea.

Just can't seem to justify $100 for tail light parts on a car I only spent $400.

I am thinking to form some buckets from light cardboard and lay some glass on them. Would it take the heat ( from the bulb ) ok?

Also, it looks like the rear lenses are slightly damaged from bulb heat. Is there a 'correct' bulb to put in these?
