You are right, Lennart that your old J63 had 4 bolts. The JE all have 5. The V6 J63 Espace's seem to share the JE dimensions.
So I'm afraid the answer to John's question would be a no. They are not compatible. JK (the steel Espace) wheels will, however, fit the JE as well as the Avantime.
I have digged a little information, and the JE wheels are 5/108/60.1 (holes/diameter/hub)
J63 are 4/100/60.1
J63 V6 is 5/108/60.1 - like the JE
