Got all the parts alodine, and ready for primer. I soon discover that some of the hole on the flanges were not aligned properly. Looks like the holes were not in the right place. I contacted the guys at the TAF, and they asured me it was ok to jus drill them again. As you can see by the picture the the hoels were just a bit off. I drilled the holes,and all went together fine. Fitted the rivnuts, and continued with the frame assembly.
