Just wanted to let everyone know how our frame turned out. We cut off the posts according to our laser measurements. Most posts only needed to have about a 1/2" trimmed off. One was off by 1 1/2". The frame went together flawlessly and was plumb, level and square when we were finished. Thanks for all your advice. I have some pictures posted on another website I frequent. (Tractorbynet.com) Here is the link if anyone is interested.

This is a link of the finished frame picture:
