I'm looking for a 1966 idler pulley and brackets for 66 427/425 car.

Classic Industries was offering reproductions. I had one ordered and they notified me they're discontinued.

Just curious. Is it the same as the 1965 396/425 Impala?

The '65 396/425 and '66 427/425 Full-Size cars had the same idler pulley setup. Corvettes had a different bracket and I think the Corvette pulley was a smaller diameter. If I'm wrong somebody chime in.

What about the '66 Chevelle L78 idler setup, same as full size, or different from the others also ?

Yes, I'm pretty sure that was the same as full-size.
