snap ring sizes. speedo gear sye install

I am in desperate need of assistance. Started my sye install and didn't think to look at all the peices before hand. Well now I'm down to the nitty gritty and am in need of the snap/lock ring sizes for the speedo gear on a crown automotive sye kit. Would love to get the heep back on the road tomorrow without having to order new ones from a different comapny. Thanks in advance if anyone could help me out.
