31 spline is Ford and I don't think the 4500 used 31 splines... GM: 27/32 and Dodge 23/29 splines...
GM switched the bolt pattern early on to the Dodge style so if you have a Dodge trans or an early GM BH, they may not match.
Advance Adapters has a conversion guide you can download or ask them to send it to you w/ lots of info.
