Too wide to pass through the fascia, or too wide to fit in the cage behind the fascia?
The Toyota MR2 and Celica use their own cage - two metal plates, one plate is bolted to each side of their own players.
It is possible to modify the plates and the Empeg sled so that the two fit together. I am guessing that other Toyota models use the same/similar setup. In the Celica and MR2, the fascia needs to be modified to allow the Empeg to dock into the sled, also.
