Which alternator for my 74 short bed

[slam59]

I have a 74 short bed with a 350 small block and need a alternator for it. What is the stock amps for this truck? I see some that are 140 amp and 110 amp as well as lower ones. I want to get a chrome one but some I see have reviews where the one wire plug was not in the correct position and other figment issues. My pigtail plug in is at the top in about the 11 o'clock position. Anyone here can recommend a decent chrome alternator that will have no fitment issues? Do I have to change anything if I go with the higher amp alternators?
