1974 318 alternator

Does anyone know which one I need for this 1974 Scamp 318 with air and power steering. If anyone has a picture they could share of one installed in a 1974 318 that would help. Karl if I can find the right one I might do just as you said and drop it off when I go down to John's, right now we are going through that 1971 340 so I will see him a few more times.
Thanks
Bob
