Ive been looking for a cheap T100 myself that I can build. It looks like a fun build! I like those axle tube spacers that you have. I may rethink my setup and go wider now!
This is the start of my custom axle build. Post number 30
Just read your axle thread, looks like we are on similar paths. Looking at your profile looks like you are near me also I live in grass valley near Rollins lake.
I have never heard anyone say they wish their axle was skinnier, especially under a top heavy fj60
