ok,yes you may use the lower Y slide bracket with the non a/c alt 3 hole bracket it would share the same lower side bolt on the water pump

on non a/c alt bracket the pivot bolt goes into the hole in the head,bracket for front of alt on pivot bolt with spaces in place,2 long side wp bolts holding bracket

now the alt is hung..

swing arm goes on lowr side wp bolt to swing up to alt bolt

the bracket you need goes across the bolts on the top of wp

this is a/c brackets,the alt pivot bolt does not goe in the head but into the offset hole of bracket with pivot bolt and nut...like you have now

all you need is a a/c comp front bracket to support the front of the alt and push it back in line

you have a belt straight to the crank bypassing the a/c comp now

it may need to be a little longer when you get the front bracket

dont look at the BB pic posted and when looking at the SB pics they have non a/c brackets and pullys so you cant get that with what you have on there now

you could take some flat bar and drill holes in each end then support the front of alt from a water pump bolt,line it up with the belt off and get it supported first then install a correct length belt

if you look at the sb with a/c,you see the 2 belts over the top of the a/c comp going to the alt,you need that front bracket on the a/c comp

then run the belts down to the crank like you have it now

clean up the web/rib on the wp neck and you will get both belts like the a/c used on the alt

if you want a true later style non a/c set up you need a non a/c 1 groove wp pully and a 2 groove crank pully for ps

they have a single groove crank pully for non a/c manual steer also when your looking so remeber 2 groove for ps

also looking at the sb pics some of the non a/c brackets have 3 bolts in the wp and the alt pivot bolt into the head...those are for an early style cast iorn wp.. may or may not work on alum wp

but the exploded pic of the brackets are what you want with 2 correct pullys to match for non a/c and ps


now you fused?
