This is vey strange - the empeg sled is exactly the same size as my Clarion & Panasonic mounting kits.

It it was 1.5mm taller it wouldn't fit into my CRX - this is *very* tight on dimensions.

At some point, slots did get smaller (vertically) - on a 1985 CRX the slot is the right width but about 3mm too tall.
