Hi, long story short, found a mint 09 Suburban 2500 with an LY6 6.0L with only 65K miles from a government auction buy. I think the pushbar acted as some sort of anode like on an outboard motor and it rotted out first because there is no rust at all on the body or frame.

Anyway, I work on the Ontario Provincial Police vehicles at my shop in Canada and I have an account with a company called Lightning Equipment Supplies for ordering police specific parts. I sent them these pictures and the reply was

"Hi Nick, I checked with our supplier of push bumpers and it says it's not theirs.I would need to know the manufacturer and model number to dig deeper into this. Steve"

I thought it looked like a Setina, but they deal with Setina. Can anyone point me in the right direction to find replacement crossmembers for this bumper?

Thanks.

 

Just a wild guess but would the W stand for western snow plow? Good luck
