radio wiring diagram/schema

hi everyone,
i am trying to repair my 75 delco am/fm stereo radio (#51yfm1) and i'm in need of its wiring diagram/schema.
where could i find one or is there someone on vetmod who has one?
i have a 70 am/fm radio wiring schema but it is not exactly the same
thanks

Wolf, You can order a Sams Photofacts AR-191 for approx $22 that will provide detailed schematics and photo layout info.
See http://www.samswebsite.com/

I have the Sams for the 74 AM/FM which is probably close but not sure.
