Default C7 leaf spring ride height adjustment support adapter

Hi, everyone, I was wondering for the ride height adjustment if anyone knew what washers would correspond to the ones highlighted in red below. I bought the tool (J 42451 - Engine support adapter kit) but it doesn't come with any washers/spacers. I'm traveling right now so I can't measure it myself and I was hoping someone knew the dimensions. Otherwise, I can go to Home Depot and try different sizes.

You're way overthinking this. All it takes is a jack stand with a rag under the leaf spring between the lower control arm bolts. Lower the car into the jack stand. It takes pressure off the lowering bolts. Use a 10 mm box wrench to adjust bolt. (Ratcheting box wrench makes it waaaaaay faster). Repeat for 4 corners.

Anyhow with that tool you shouldn't need the spacers. Just snug up the wing nuts and then turn the middle bolt to raise the spring. Same thing the jack stand does.

I put a hockey puck on the jack stand, but the bottom line use something to protect the spring. Floor jack, jack stand, puck or rag, 10mm box wrench. Takes a matter of minutes for each corner.
