I just put a reproduction 4 core in my Camaro from HBC.
And we also used one from HBC in the Grady Nova.
Nice quality, a little $$
I have been running mine on the street and all's well.
And by the way, the tag does not come with the rad. And I forgot if the shroud brackets are included, ask about that if you call them.
Look at some of these.
