Wide 5 backing plates

[doghousedevil]

I have 2 backing plates I scored. Neither have the spot where the cable enters the plate. They were on an I beam axle I got with the wide 5 wheels, drums etc. I was wondering if maybe I got lucky and these are the 39 hydraulic brake version? The second pic is of the cable on the 37 frontend I have

This is the one I found. The first pic was the 37 ones I have

I can't tell from the pics, but if the second pic you posted has a hydraulic cylinder on the right, you scored...

Everything pictured is for mechanical brakes.
