I don't know specifically for this application, but typical Ford numbering convention of that period will use the same part number for any application that uses the exact same part. I would expect that any similarly equipped Cleveland powered Mustang from '71 to '73 would use the D1AE part. I say 'similarly equipped' because some options, such as air conditioning or power steering, may require a different hose, and therefore, a different number.
It is conceivable that the hose, for any unknown reason, was changed in some way for '72 or '73, and the part number changed accordingly. If it matters, please verify.
