John, Many folks have figured out how to get the height with what you have, I made a small wood platform that was the size of my HF Jack platform, using three layers of 2x4 scraps alternating with some scrap plywood/osb sheathing. I jacked bike up with the lift high enough to rest it on the jack stands. Loosened / removed the bolts while there. lowered the jack, bike still on jack stands, added the "platform" and jacked bike up high enough to slide the old out slip the new in, then lowered it back to the jack stands to finish.
I think someone here lifted the bike keeping the back tire on the ground by lifting forward of the balance point and the angle gave them the clearance to swap.
