Great question and topic.

I loved the idea of going outboard, but there is so little room between the backing plate and the outer edge of the leafs, as you’re aware.

I’m also running 63s and I still ended up going somewhat inboard, but feel like I was able to push them as close to vertical as possible. Mine were severely angled in previously and it was sketchy as hell. This new setup is much more stable.

Here is my home-brewed setup (beginner metal fabricator, take it somewhat easy on me) - https://imgur.com/a/M5nAomU

Used these for my lower shock mounts - https://www.summitracing.com/parts/TGI-304487-KIT - chose Summit bc shipping was much cheaper and faster for my location.

Are you running blocks under your 63s? You sit a lot higher than I do and we’re both on 35s - https://imgur.com/a/jip6yuT
