I'm in the same place. My A8 is ~Oct.16. Had a little trouble with the dimensionson the right hand side, but the inside of that piece is 90.1 (frame measures 90.5), Like this, the X-stepper just has clearance when the left lower is in place, but as soon as I assemble the full brace, I loose the clearance. I can home Z, but its not usable like this. Printed it last night, and not had a chance to trim down the part (except cleaning the corners with a knife). The offending side doesn't seem structural, so I'll try filling it off - but I worry the force of this bracket is removing the clearance. Obviously, if the right-hand bracket is tightened more, the clearance for the stepper should increase.
I'm sure there is a fix, i'll keep you informed with my progress, but it won't be till the weekend. My gut feel is that the design of the printer isn't changed, and we're just unlucky with tolerances.
