This is why most places will sell you a kit with the most common sizes. I bought mine used on 
ebay with the tools and about 80 shims for ~$20. Once you've done it a few times, record the 
sizes as they are installed, and you will know for next time what size to use. I just did mine 
last week after 35k and they were still within spec... :-)
