Can a late model stepside bed be used on a 64?

[ScottH]

I'm thinking of picking up a 64 swb that has the original stepside bed on it now. It is in rough shape so the seller is including a newer bed circa 75-79 (I'm guessing). I would like to use the newer bed but install the original fenders & steps on it to keep the correct look. I'm guessing they are the same dimensions but obviously the holes would be in the wrong places.

Does anyone know if I can use the newer bed with the original fenders & steps?

Any info is appreciated.

Thanks
Scott
