Teac X-3 Tape Deck front panel Question

Teac X-3 Needs a belt. Got all the screws off the front panel and the parts that come off. Even took the back off.

The front panel is loose on top/bottom  and both sides. Can get about 1/2 inch if pull lightly BUT seems like something in the middle by the heads is stopping it.

A close look shows that it should lift right up from there. No need to take off the heads assembly. Tried looking for some screws from the back with no luck.

Got a schematic and looked ... either I'm blind or somethings wrong. Can anyone tell me the exact procedure to get this panel off so I can put new belts on and see if anything else if needed. I would really appreciate it. Thanks guys.
