Re: More Speedo. Ratio adapters, 65 A833

Tom, we do build the straight style adapter along with the special cable and clamp. The original Stewart Warner adapter was a darker gray color and the edges were much more rounded than the ones we could buy.

We built ours with a .75 reduction as it gave better coverage. We can custom build some ratios as pinions are getting hard to find, if I have the required gears in my collection. Once these parts started getting "rare" everybody thinks they're worth a mint. As an example, I recently found a box with a collection of gears, axles, spacers, screws; a lot of little bits and pieces, some of which fit the adapters we build. If I cupped my hands together all of the parts (including the ones I couldn't use) would fit without spilling over, and they wanted $700.

There is a chart floating around in the catacombs showing the pinion required for a variety of tire and axle ratios... I bet Gary H. has a link :)

Instead of hijacking this thread I've started a new one with more info about ratio adapters and rare parts. Feel free to contact me offline if you have questions.

Thanks,

With the speedometer topics, i thought id post one as well. :-)
Shortly after putting the 8 3/4 in my dart in january, I disconnected my speedometer. It was running 25mph fast, and it was driving me nuts.
The tsm says I should have a purple gear and the .8:1.0 ratio adapter for the 4 speed, rear end gear and tire height I am running. Just
I've been keeping an eye out in the wrecking yards, crawling under anything old mope that makes its way to the lot, don't even know what they look like, but hope to see something different on one ofem to finally score one.
Anyone know anything.about these and if, like I assume, up to 65 is different than 65 later, and where in the trucks and vans, I'd expect to find one? I've made the assumption I may find one more easily on the lower geared vehicles.
Thanks and regards, -Tom
