Help, broke my brakes...

[elks]

So after doing a complete brake overhaul, my wife was getting ready to pump the brakes and I was preparing to bleed em. ON our first go around, there was a large pop when she pushed down firmly... After looking we discovered that the push rod from the pedal that exits out side the fire wall snapped in 1/2. Looking at it it is potted metal and not something that looks Like weliding will fix.

Any idea where I can get a new one?

I found this on ebay, but not sure if there will be a difference? I am running the 1 ton booster and MC on my blazer, but this part should be original. I look at lmc all they list is the rubber boot...

Here is the EBAY one... Is vacuum assisted considered power or manual?
