Your 727 is the same as mine and every 62-65............ The speedometer pinion gear is in the tranny - at the end of the speedo cable - and easily swapped out. Here’s a chart that
might help select. Also you can use a MPH app on your phone to check the speedometers accuracy..........

Subject: Re: Welcome new member - 1965 Plymouth Satellite
I’m running 3.55 Sure-grip rear diff on P255/70R15 rear tires and after talking with Robert at A&A Transmission in Camby, IN, because
Rick was not in, he said they don’t make a gear for the 1962 Polara 727 Torqueflight.
He said what they do is make up a speedo cable with the corrected gear already on it. That costs about $500.
Well, because I don’t want to break the new cable I currently have and most certainly not a $500 cable, I’ll do
what they said everyone else does, by holding the Polara under 120 MPH. The Max-Wedge is pumped up to the gills with well built components. I will just have live with the 10 MPH lower than indicated.
No need to spend $500 and then end up twisting it off with the force of a 600 HP motor I’m running. Or, if I race
it, disconnect the Speedo cable.
Thanks for your advice and if anyone else has other good suggestions I’m open to any of them.
Used or NOS will be the only way to find them.............
Got mine from McGuyver!
(Went from 17 tooth to 19 tooth to correct my speedo after going to smaller dia tires)

Brewer’s always lists some:

Does anyone have a source for Transmission Speedometer Drive Gears.
I have a 1962 Dodge with 727 3 speed and Sure Grip 3.55 rear axle ratio.
The speedo is about 10 mph (70) faster at 60 MPH and I’d like to get it closer to actual speed if there any for the 727.
Summit Racing has a set but I’m not sure if they are for the 727
Below is his introductory message.
I recently acquired and am continuing the restoration of a 1965 Plymouth Satellite. Except for the automatic transmission, it is almost an exact duplicate of the one I owned in 1966 when I was 21. It's been a long time since I twisted wrenches
but I am enjoying it again. Looking forward to hearing from others with similar interests and a willingness to share knowledge, advice and suggestions. Bill
