So is there another endplay measurement taken once I start re-assembling the main barrel of the transmission?

I wondered that when I kept seeing intermediate shaft endplay shims for sale. Is it a good idea to go ahead and order one of those endplay shim sets to have on hand for this build?

I looked at the washer kit that I bought for this build and saw that I have three of the three tab washers and a new hardened steel race. These look identical to what is pictured in the end play shim kits. Do I have what I need, sir?
