For future reference and searches, I showed a rear end builder my gear patterns (.039, .037, .035, .0335/.034, .032) and he said the .0335/.034 shim and .008 backlash were on the money for my Richmond set, so I'll be rocking it as shown below. It looks good to me also but what the heck do I know.
Ok, here it is .008 backlash with with a shim on .0335/.034.
