^ Looks like the OP needs a 240 lower console type radio box.
IIRC there's no support brackets in the lower central console to hold it in place. If a radio box isn't used, the head unit can be mounted on the transmission tunnel via a bracket and then a black facia plate made to fit over the front of the radio and cover the hole.
Later 240s did have their head units fitted up top where the space for the accessory gauges usually fit.
