oldsmobile brackets and pulleys

[85cutlass6.6]

im coming closer to being ready to put the 403 in my 82 cutlass, right now i am trying to find a set of alternator and power steering brackets and pulleys, i have a set of 69 350 brackets in line along with a new set of olds billet pulleys, will these pulleys work with these brackets? My dad is skeptical about mixing the brackets and pulleys

I'm with your dad. Not that it won't work, but It's always easier to use a complete matching bracket/pully set so you KNOW they'll work.
