D150 Manual Gearbox Spline Count

I modified my coupler 20 years ago, got fed up with fixing the failing spring. Hacked up a chevy one and welded it to the dodge spline. Still as good as the day i repaired it.
Could section off the splined part and run with it. AC5EC584-C649-466F-AA88-39D781DEC55E.pngIf you google the number, you will find the chrysler number, may find the spline count.
