Mine is a 76 but reckon it should be similar. 
It is original and not changed. 
A bit grotty - but original. 

There is a “slide?” Or “slot” at the rear vertical and then there are 4 screws across the top that have caps.

Ah, thanks Barry. That makes it easier. I'll find some nice s/s screws to hold them on. I was confused because all the new cards I bought had pre-drilled holes for fixings, except those two.
