Ian,
no, just find a glove box from one of those early model 124's and you will find it looks just like the glovebox as fitted to the pre 78 X19's in other parts of the world... simply fit under your existing dash, but you won't be able to lock it as the lock mechanism is part of the crash pad assembly. If you want a used and pretty cheap124 glovebox I have a few spares, PM me.
Tony, so that's why we are RIGHT hand drive... 'cos it's just right that way!
Sitting on the left has always seemed so sinister... (that's a pun)
