I'll post more detail next week when I get it back. I believe it is 3/16, but I'm not positive.
The shackle tabs are 1" and are part of the frame mounts.
As for the rear...it's comming. the steel is sitting in my garage, but it - 20c here right now, so I'd rather be indoors surfing the net!

As far as cost goes...I was able to make a trade. I built a work bench for the owners garage and in turn, he made me the bumper.
