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

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.
