Small block water pump pulley question

o.k. , here's the issue . you can't use A/C and non-A/C pulleys on the same motor and you can't A/C brackets on a non-A/C motor . Everything must start with the crank pulley , this must be correct . then go to the water pump pulley . It must match both in diameter and in offset . Once that is aligned , next comes the alternator pulley . duel pulley alternators are for A/C cars and misalign with non-A/C water and crank pulleys . Remember 1/8" is no good . I've seen lots of cobbled up pulley drives in last 40 years and a lot end up in a bad way . You can mock up what you need and get on the forum for parts but start with the correct crank pulley first .
