You'd probably have to speak to Ken about that ... I have only ever seen his AE86 Sprinter parts and a body kit for a 20 valve AE82.
Not sure about those EP91 Starlets but there's not really much in the way of bodykits for them. You'd have thought someone would have made a replica of the Glanza V bodykit by now wouldn't you?
Otherwise, there are always lots of other places - you'd just have to call around to see what's available.
