i am currently fitting a evaperaterbox from an E3.i have noticed that the mounting plate to the tans tunnel doesn't line up with the holes,no problem there.the box itself seems a little tall,my question is,is there a difference between the E9 unit and the E3 unit.it can be shoehorned in.also i have noticed that the E3 aircon control pannel is taller,i think that it has two extra slats.if any one has a contol pannel for sale let me know. thanks matthew
