Going on 4yrs since I gave an update.
Still have the project which has been sitting and just collecting dust for the 4yrs. Moved 3 times in 9 months with all my stuff plus a illness.
I have finally gotten to point where I have it back in shop now vs storage.
Slow going but have made a bit of progress over past month or two.
I was able to replace the box floor and make some new pieces for the 4 corners of box. Still needs a bit more welding and grinding then will be ready for primer. Many months to just get that much done. Box sat in middle of shop floor for a couple years waiting.
