Thanks for the info. I hadn't thought about the front tire width. I guess I will have to consider that. I plan to use the Jim Meyers (GM spindles)front end with manual steering. So, I will need the narrower tires. I want wider tires out back than 215 I think. I will have to try to find pictures of a truck with 215s all around. I may want something like 215/70s up front and 235/65s out back. I can do the math and figure out what combo will make the outer diameter about the same.
