360 crankshaft end play

I don't want to put a damper on you ,but you really should put a dial indicator on the crank snout or somewhere accsesable[spelling].and check it with that..heres why...almost nothing iv ever seen wear flat..a surface like a thrust bearing like an armature will wear with peaks and valleys..if you can get a feeler gauge in there that's what you will be checking from peak to peak.a false reading.then when a crank is pushed all the way one way or the other,it will mesh then you could i have more clearance than you think..002 to 010 aint much..its your motor, but a used t bearing is what you are checking..put a dial ind on it then pry it forward and back and get a true reading on a used bearing..j
