Help ID K10 Steering Gear - 67 or later?

[ohboy321]

I have a 67 K10 with power steering, and I want to replace the steering gear. Although my VIN and cab are 67, I am not sure about the rest of the truck.

Someone in another thread mentioned that the 67 K10 did NOT have a dimple in the frame near the steering gear.

Can someone help me ID the steering gear/frame from the picture below? If it is not a 67 gear all the better, as I do not see anyone listing refurbished units for that year. Plenty available for 68-72 though.

Thanks for the help.
