Disassembled a few 4 speeds this month. Is it common to have the speedometer gear distorted or destroyed?  I've only taken a half dozen or so apart over my lifetime and the last  2 were really bad. Also, I found replacements on Amazon for $27 if anyone needs any.

Maybe not set correctly. Dang things are expensive now.

I have rarely seen gears that worn , could be wrong oil used or the drive not clocked / positioned with correct mesh

I think there are a lot of people that don't realize the housing needs to be clocked correctly depending on the gear used.  If I had to put money on it, that's what I would bet on.

Maybe a seized cable ?

yep...those actual gears are plastic, and the gear in tranny is metal.   If the cable seizes while your driving the car (like too close to a header pipe) then something has to give...  and that something is the plastic gear !!   Had it happen to me once..

The clocking is important.

All good points. One thing I always forget is the last 2 I took apart are from 1968 and 69. Not bad for 50+years.

Last time I checked, Brewers had a large stash of used speedo gears at a much lower price than new. I bought mine from them and it was perfect.  :ohyeah:

I've bought a lot from brewers.  I was a little disappointed the last time. I felt they gouged me on the freight.  Mailed it to me in a padded envelope and charged me almost $20. Nothing but clips and small hardware. Lucky if it cost $3 to ship.  That's why I went to Amazon this time. Same gears at half the price landed at my door.
