Chevrolet parts arent the same as GMC on my application. This stuff is heavier duty and significantly larger. Plus being a COE means the worm gear is above the pitman shaft, while conventional models are below (or something like that). Although the pictures do look the same between the two makes.
The lower race is actually machined into the adjustment screw, while the upper race looks to be seperate. Maybe by now enough of the grease and rust has fallen off in my tank and I can see it a little better. But there is no way to access this piece that I can see. I have NOS bearings to install in the box so no worries there.
