Best sources for die-cast models?

Specifically the 1970 LT1.

A friend of mine bought this car almost a year ago and it's been in the shop since the day he bought it... now in the final stages of restoration and almost ready for entry to the Vette association. I'd like to see if I could find him a die-cast model of the same car. He's been able to find one but it was really small and had little detail to it.

Any tips or help offered would be appreciated!

Cheers

i have purchased some sharp camaro's off of ebay, they come with certificates, and the cool thing is, you can interchange thier wheels, hoods, grills. i mean they rock, but some of them will run you $50 and up.
