I bought the wheels off of Craigslist. They are Silverado wheels off of a 2019 or 2018 (I can't remember which). I got the set for $250.

I've been doing a bit more. I changed out the headlights and driving lights. The headlights don't look as good in the picture, but I'd give overall fit and finish a B+ for them. They are Depo lights and I've never had a problem with this company in the past. The driving lights, OTH, were a pain. They look OK, but they aren't contoured like the factory housing was. Every turn of the screw made me think I was going to break something.
The battery cable was another fun one. I ended up with this terminal replacement part. I tried to find the whole harness, but just couldn't find it new. GM doesn't make it anymore. I wasn't happy with the previous owner's solution. I also spoke with M&H who are simply awesome folks to work with, but they were reluctant to do a terminal with an 8gauge and 10gauge wire in addition to the 4gauge starter lead. It was excellent speaking with them, however, and I learned alot.
