Spacers for Pulleys - SBC

Because I am having to improvise the alternator mounting on my SBC in my 62 Studebaker, I find that I may need to move the pulleys out maybe 1/2". I'm using a short water pump and the alternator will be easy as I can just slide it out with my design, but if I need to move the crank and water pump pulley outt to match, can I just use 1/2" thick spacers under each bolt on those pulleys? It seems like this should work as long as they are all the same thickness so there's no wobble. Any thoughts will be appreciated.

Are you planning on using a single groove ? if so you might want to go to a double or even a triple groove on the crank if you can find one that will line up ok. JMO i just don't like the idea of the spacers being on each seperate bolt IMHO i am not real sure but seems like i seen a spacer that goes behind the pulley and has the lip the hooks in so to help lock it in place when tightening it down. But don't hold me to it but i have seen alot of adapters/spacers in my time but pretty sure they do make one. maybe someone else will chime in and know more on the subject, i do know it don't take much to through it all off and i mean it might look like it's running true but it might not be. Been there done that is why i say this.

Why the hell didn't I think of using 2 groove pulleys! I was going to run a single groove because I only have an alternator. DUH.
