Hi, This was a better clarification sent to Al a few days ago.
Al, First, Ed Burkhead has it right. Second, Bill Biggs had it right too. Don't rely on just the 75 inches plus only. Third, READ THIS. (important) http://skyportservices.net/Spacers.pdf <http://skyportservices.net/Spacers.pdf> This will give you all the information you will need to know about spacers. I did this back in 1990, with a few improvements. Most of the time the 5/16 spacer I specified back then will work. That spacer should get the sills nearly level, and you can get them from Skyport. If it does not level the sills, you can take the guess work out of it and use the formula provided on the last page. It will give you the EXACT thickness of the spacer you need. Make sure your tires are inflated correctly, and the donuts or springs are installed correctly before measuring. Let me know how you make out. Bill Coons
