Howdy!
Are the '63 and '64 bezels the same? I'm not sure...
I think somebody makes (made?) some repops...but they want a small fortune for them (north of $300/ea, IIRC). Keep an eye on ebay and look for some decent bezels...that's what I've done. I've got one decent spare, but I really need at least one more...
Taillights are another problem...
Let me know if you find anything! (Wonder how much it would cost to run a set of headlight bezels, anyway?)
