Jack's Comments:

This is the best available 428 S/CJ anti-backfire diverter valve mounting bracket on the market today. The engineering number and FoMoCo die stamps are all the correct font, size and location. The smog hose and diverter valve is held to this bracket with a #9 Wittek clamp that we stock. 

Q: What clamps are correct for the 428 CJ smog hoses?
A: The long hose (passenger side) uses a #7 Wittek clamp at both ends, the short hose uses a #9 Wittek clamp at the diverter valve and #7 Wittek clamp at the check valve. The S-Hose uses two Wittek tower clamp.
