Some year 351's used the same alternator bracket as the Mustang 5.0L I don't know what years, but I have sold them before to Mustang guys. I would say most others will work.
I have a set of March 351 polished brackets and pulleys that I pulled off mine when I added my YSi. If you want somthing that looks great, I will sell these.
The alternator and water pump pulley does not go with it, but the complete PS mount, pump and pulley does come with it.
