If it works it's OK
Just a tip. This will not bring a Saginaw 4 speed around when as a replacement for a white 19 tooth gear. It installed easily but doesn't engage the drive gear. The speedo went dead. It's not fault of this gear. But I thought I would warn anyone who might think this can be dropped in a Saginaw to compensate for 3.73 gears without other internal transmission modifications. It won't work.

Worked perfect
Changed rear end gears in my 1973 camaro Th350 from 2.73 to 3.73. Quick fix that fixed the speedo.
