Help - to install stock radio ?

[hooverfish]

Can someone tell me steps to install stock am radio in my 72 a/c dash? I bought a decent AM and want to replace the cheap aftermarket cassette. Should I remove the glove box liner and take the radio out the side ?
Any help or tips appreciated. Original speaker looks to be intact and I have the correct wiring plug and bracket on the rear of radio.
Or maybe point me to a previous post with directions? I searched but didn't find too much.
