1963 valiant front runner sizing suggestions needed

With 4.5 backspace how did you fit a 10" rim? Is your axle narrowed?
Yes. I think it ended up being 49.5" flange to flange. I tried to get it as centered in the mini-tubs as possible.

Here is a link with my build and the mini-tub specific part of the build. Don't go wondering around too much in my build thread. You might decide to turbo your Early-As also!
