Krautrock,
My recollection is fuzzy, but is the PST box made of cast iron and slightly different in appearance than factory? I thought the factory box is cast aluminum.
The Flaming River box is cast iron. PST might have sold the Flaming River box at one time but they now sell the aftermarket aluminum box. I don't know who makes the aftermarket aluminum box, I assume it is an offshore product but I don't know. I think they have been around for a few years. There was a thread over on FABO a couple years back about those boxes. I've never seen one in person myself.
