Need advise bolting a np445 to a 325 poly

Is the A833 input shaft 23 spline the same as the np435 np445 23 spline. I could pull the trans and bell housing and mate it up to the 325 and measure that spacing. I have been told the adapter 3/4 of in wide. I hate to pull transmission to find. Now also been told had shave off a little input shaft when bolting a a833
