Just looking a few pages back in the thread. Man I’m in love with the idea of being able to convert the front springs on the existing 60/62 axles. No need to source other axles and the 1:1 you mention has to completely eliminate the damn stink bug stance most of the leaf lifts create.
I used WTOR a few years ago for a steering box refresh. I ground a very distinct notch into my housing, the same housing was returned to me. Box has been fine since.
Just my experience.
That said I question what anyone really does to improve these other than seals cleaning and a paint job...
