The 8 lug steel wheel in question will work. Dexstar trailer wheels work good, Wheel Vintiques has them too. Also, Ford E250/E350 van rims work good also. Make sure you have 4.25" or LESS backspacing or you're dead in the water. You won't clear the tie rod.
You'll have to install hubcap clips. Most vendors have them. Here's how.

THe 54/55 trucks use a Bowtie hubcap. I've NEVER seen an aftermarket replacement for them. All that is availible is the script type that the 53 and earlier trucks use. My 54 had Hubcaps on it, luckily. I bought a parts truck and was able to get 2 more. I'm treating them like gold bars.
