old style mazda dimensions

Hey, all you guys with pre-1984 trucks, I need your help. I need the dimensions of those trucks.
here is the measurments I need:

hub to hub front and rear
wheel base
the length of the front bumper
and the engine bay (would a 5.0 HO fit there?)

would all of these measurments be the same on a longbed

I will be posting info about the project if this works out.
thanks,
Mike

thanks again,
Mike
