old american racing torq thrust mags

irrelevant

 

Post a picture, and see if they have "american racing" cast into them. If they do have the name cast in, they are a aluminum. If they don't have the name cast in, but instead have a sticker, then they might be magnesium.

The early 5 spokes were indeed magnesium.

 

And you can get them for $54 each.
