The pawls are attached to the lock cylinders on the backside of the handle. They are the Z-shaped bracket. They are longer than the regular gmt400 handle pawls. They don't require modification.
If you want to use your existing lock cylinders, you will have to take off your old pawls, and swap your driver side lock cylinder to your passenger and vice versa, then re-install the pawls on the lock cylinders. This is because the locks turn the opposite direction for some reason. These pawls are held on by a snap clip...be careful pulling your old one off and don't lose it!
Sounds like you scored a good deal, but I would definitely go back for the rods. I drove an hour one way to get set. It was a shady situation well off the beaten path and out of cell range, and the guy wasnt there, but his drunk buddy was. And the truck's front end was suspended 8 feet in the air from when someone bought the front end for a mud truck. Then he couldn't operate the tow truck to get it to lower down, and then the windows were down....I still have nightmares about this transaction! I picked up a set of re produced handles and a new set of gm locks with keys from a guy on here who I think gave up trying to find the rods and pawls. I also picked up new plastic gm clips (there are two gm part numbers) from gm parts direct to have as spares, they are a little pricey for what they are. I've probably got 125 bucks in my set up and haven't mounted them yet!
I get it now. I didn't see this post before i posted my reply to C30454. Thx. I'm good with a separate key for the doors. Oh and you know I'll be driving 180 mi round trip for those rods. Lol
