Billet serpentine belt set-up

Is there a manufacturer of a billet pulley serpentine set-up for a Buick 455?

 

Pretty sure there is... forgot where i saw it recently though.

 

March has a billet set up for the BBB. Also seen guys use V6 parts to make their own

 

I have this one from Metco but they only made two sets and the other one is on the car in the photos pictured.

 

I used the March system, it’s a bit tricky getting the pulleys lined up

 

March System. With A/C. It's also powder coated clear. No polishing needed on the brackets. I think its 57 LBS lighter that stock.
