I just bought a Fastrax alignment tool. Follow along as I use it to adjust camber and caster on my 1962 Cadillac Coupe Deville. There are 2 different models of this tool, based on your wheel size, here are a couple of Amazon affiliate links for both:
For 13" to 18" wheels https://amzn.to/3ehTzbx
For 17" to 22" wheels https://amzn.to/3ej1mpt
