From experience, i'd suggest going to a dealer and measure the shims you're buying with the same equipment as you've measured your existing ones with.
I've sent shims out mail order only to get a phone call saying i've sent the wrong ones out only to find they've been measured with different equipment to my own, especially closing shims. There's also some "tolerance" on the new ones to and if you're shimming tight, to old fashioned tolerances, you could have problems.
