A833 inside swap

Would love to just change retainer but there is a 1\2" difference in the bolt pattern. There is a very big difference hole size in Bells at least an inch. Motor and older trans came from same car 65 Dart GT so it's drilled for pilot. Can one buy a retainer for older trans to adapt to newer bell.

Thank You for any help

I think Brewers Performance can help you with a retainer that will work with either trans.
