Default '76 T/A pulley setup : A/C vs non A/C pulley order

My '76 was an a/c equipped car using the flat single grooved pulley to the balancer( for the a/c), then the double grooved pulley for alt and power steering after that . I'm going non a/c and want to eliminate the single pulley on the crank. If I use the the original water pump pulley I am thinking that ( to keep all the pulleys properly aligned) I will need to use the ring spacer first( that's the one that would normally go on last) to act as a shim to get the double pulley where it needs to be. Of coarse that means that there won't be a ring spacer where it would normally go. Does anybody see anything wrong in my doing this?
Thx, Larry

Put the one in the back and get another for the front. Make sure you have adaquit thread engagement. Maybe a little blue lock tite

The crank pulley on an A/C setup is spaced from the balancer via the A/C pulley. If you don't space it, you will have an alignment issue if you continue to use the A/C water pump and power steering pulley.

The 'ring spacer' is actually a reinforcement plate, and usually goes in front of the pulley, so it doesn't space anything. Not sure if it's the same thickness as a pulley, but if it is, yes, you could use it as a spacer.

The A/C water pump and crank pulleys are desirable, since they drive the water pump faster than the non-A/C pulleys, helping with cooling.

Some aftermarket balancers don't have a beveled edge, and the A/C pulley won't seat right. Something you should also keep an eye out for.

There's no issue with running the A/C balancer pulley aside from that, just don't put a belt on it.

Began providing an extra round reinforcement ring to mount behind a two groove AC diam crank pulley as part of a version of our 11 bolt timing cover/PS pump bracket changeover which i first began putting together in the early 90's.

Over the last 30 years, most of these 11 bolt PS conversions have been provided with non AC pulleys for '65-68 owners. Beginning in the mid 90's, I began getting more & more requests for the correct AC diam pulleys to be used in a non AC car & in order to help combat overheating while getting the spacing correct. Seems next to no one wants to run a single groove pulley behind their engine's two groove crank pulley when that single groove supplemental pulley isn't needed.
