Inner Tie Rod Replacement

[75sierraclassic]

I've got a 2003 Silverado standard cab short bed 2wd 4.8L with rack and pinion steering. I'm trying to replace the inner tie rod and got it all torn apart tonight. On the rack, there is no flat spot to put a wrench to hold the rack while you unscrew the tie rod. See pics. My service manual says there should be a flat spot to put a wrench. Anyone know whats up and/or how to remove it without damaging the rack? I have the tie rod tool to make removal easier I just can't figure out how to hold onto the rack.
