Did I read that right? $255 for the set from that link you posted? That looks like a good deal to me.
A buddy of mine had a genuine set of NOS Tbird valve covers like the 1200 job in the other link. I took a look at them and told my friend, nah.... I don't think so. My friend went up to Hershey, PA and sold them for $425. I thought that was too much, lol
