Stop in for a cup of coffee
I bought a pair of Espo's probably 10 years ago for my 66. The gal asked me if I had 5 leaf or 6 leaf. My cr was locked up in the storage garage in the middle of the winter. I said "probably just 5 leaf". Well, my 66 has HD suspension option and it had 6 leafs on it. I installed the new ones anyway. They softened a little bit the first year and have been perfect ever since. 5 leaf, stock height.
