I recently scored a job lot of 8 door handles, a mixture of front and rears including early and later (1990) tibbe/spindle key fronts. In the fullness of time I'll gumtree the earlier front handles and one or 2 of the rear ones.
I've since discovered that for the Tibbe key front door handles there are 2 part numbers. JUM2043/4 for the pre 93 cars and JLM11286/7 for the later 93-94 models.
From the outside they look exactly the same, so the the question to the learned members here is, are they interchangeable? I suspect/hope they are and it's just a MY93 wiring plug change.
