Stewart Warner speedometer ratio adapter

[Quikshft]

Guys is there a source for parts for these units that correct your speedometer reading? I have 33 inch tires on my truck and the speedo reads slow. I believe there's a parts kit no 82954 that contains all the various gears needed to get quite a nice range of output ratios but can't find it anywhere. Obsolete? Any help or insight appreciated.

Years ago you could buy them with different gear combos so you could custom build your own. I think the kits are obsolete now.
Adaptors are still available.
Look in here in ‘speedometer world’.

There’s calculators there too.

Thanks! Looks like the 54RA2 might be something I can utilize.

Google Rowand Speedometer Co This fella sells the ratio adapters and sets them up to correct your speedo reading. You have to know the actual speed usually found with an I phone Speedometer App. or GPS and the vehicle speedo reading. He'll set the adapter up and it'll be right on the money. I got one for my 68 and it works perfect. Cost was $144 shipped to me.

I had one of those on my 3 speed but never got it to register too close. I changed the driven gears and that got me a little closer,
