Can anybody help me wire 2 relays , 2 diodes , switch 0n-0ff-on and 1 motor so that when switch in ON position motor rotates in direction A and when switch in other ON position motor rotates in dirrection B. Relays have to be wired the same way, and not using 87A, and 30, 85 to ground. 2diodes have to used.

Why so many specifics? Also not using 87A you can't do a reverse polarity relay system. I say you are screwed unless the motor is self grounding. Also technically if the relays have to be wired the same way it won't work regardless because they will go to the same wires.
Why do I smell homework?

Is there any reason why you can't use 87A?

I know that there's 2 ways actually you can do that , but i just wanna find out how to do with 2 diodes. But if i don't figure it out i'll always can use 87A. Thanks, it were just only you who responded to my question. ------------- questioner

Why don't you just use a DP-DT-CO switch and screw the rest?
