wheel options for 2nd gen?

[Bram]

Hi there,

My '75 Camaro still has its original steel wheels.
I considering an upgrade to aluminum wheels,
because they are lighter, and look more fresh,
and I can dump the shabby tin, that covers the
steel now.

What would my options be?
What rim size is best suited when you want to
have aluminum wheels on a 2nd gen?

Also, is there a gallery somewhere on the Internet
that helps to get an idea on how different wheels
look for 2nd gen?

thanks,

Bram
