A833 trans alignment issue? Help

Quick question.....
When I install this trans it goes in pretty smooth until the last 3/8 of an inch where the shaft housing has to fit into the hole in the bell housing. I have to use the trans bolts to suck it in. It fits but it's snug. Is this normal?
Folks tell me it should slide right in. If this is the wrong bell housing it's only off by a couple thousandths. Any opinions?

Mine was "snug" but not overly tight. I bought some bolts the same thread/diameter as my trans bolts only slightly longer. I cut the heads off and hand threaded them into the bell housing before I installed the trans. They act like guide pins and help keep everything straight and aligned, so there is no binding.
