I may be wrong, but it sounds to me like he has the roller bearing adaptor Professor Fate shows but wants a bushing in there vs a roller bearing.
Which may or may not exist, because the OD of that roller bearing might not match a bushing that has the correct ID for what the OP need.
There may be a different adaptor available, but I don’t know what the OP is trying to put this NV3500 in.
***edit***
If this is an NV3500 into something this needs an adaptor that fits a Mopar/AMC crank register, this may be the necessary bushing
