Thanks folks! I've done some more looking and I actually found brand new stock wheels online for $79.99, but I also stumbled across a local guy who might have five stock rims. I'll find out next week. Given that I want to try and stay close to stock center hub caps I think the logical choice is to stay with stock rims. Now, thanks to y'all, I feel confident I can mount a good tire on stock rims. I was surprised to find a lot of tire choices online for 15" wheels, so that's good news as well. Now to find my paint color so I can paint the wheels to match the red truck and I'll be good to go.

I finished the brake job last week which included new wheels cylinders, spring kits, rubber brake lines and brake shoes plus I had all the drums turned. I had to remake the rear steel brake lines too. Going to bleed the brakes and then order a conversion to power brakes with a dual master cylinder. I'm thinking about the Brothers Trucks part for $300. Any one use their kit? I haven't seen Brothers mentioned here, but I had good luck with them when I had my 62 C 10.
