Steve..pay careful attention how the top lever lock..(the triangle plate on the right hand side goes).. and note there is a steel plunger cap on the upper spring.. that will go flying as you take everything apart.. While easy to do.. a quick drawing.. or digital picture will ensure everything goes back in the right place..
Steve.. If you get in hot water.. and SKYPE.. I'll walk you thru it.. It's not hard to do at all.. And YES.. If you are really careful.. you can push the pin out just enough from the left to the right..not to fumble with the top lever lock..(the triangular piece of metal and the tiny spring and plunger)..but that has always been hit/miss for me..
For all of my friends who have never done this before.. See me at the GRAND next year.. and I'm happy to show you how to do it.. All Good.. Mike
