A different Speedometer gear question?

Just ran across this thread.
For the record, doing a rescaled speedo is pretty easy. I get a table of values from the customer that they generated, either by math or with a GPS. Then I re-scale the speedo. Since there's so many different tire/diff combos out there, I don't really have a pre-made selection of different speed scales saved. I always ask for a speed table.
I've done this for tachs as well. Ford V8 guys like to tweak the dashpot on the tach to give it a 7000 rpm end point. I've done a half dozen or so sets of this order.
And I don't do indiglo gauges. sorry. heh
And the thing that curly posted Lonnnnnng ago in the thread, would work pretty well. I could do a dual-scale gauge face. That would be pretty sweet actually. You can swap diffs as often as you like and leave the stock gear inside the transmission. When you swapped, one scale would become accurate and the other would no longer be used.

update. Nothing I found was working from the OEM mazda parts catalogs. but look what I found. looks like they have aftermarket mechanical speedo drive gears for 3.909 21T which mazda currently lists as no longer available and a 24 or 25 tooth for a 4.778

I think the Chikara one is 24t based on trying to count teeth in fuzzy pictures. Its probably closer for a 4.6 than a 4.8. but better than a 22t or a 23t. a 25t would be better.

Here. I had some free time and did a mockup of the dual scale gauge.
You would LITERALLY not need anything else. Just pop a gauge in the cluster and let the stock speedo gear live a happy life in the transmission housing. Swap diffs at your leisure and just pay attention to the correct side of the gauge.

For just the speedo, I'd be happy to do it for $30. That's my rate for singles. The design already exists (and was posted) and that dual speed scale SHOULD be accurate. It's just a mathematic scale though and not based on any GPS readings.
To do a whole set, I'd ask $169. I'd need to expand the design to the other four gauges. A set is $129 and I charge $40 per hour for design work. I don't see it taking more than an hour.
Custom gauges are always charged based on the time it takes to do. The $289 price on my site is just an estimate at 4 hours of labor and the base gauge fee.
Sorry that this post is so price and marketing heavy. If any of the staff is unhappy, please edit. Don't mean to anger anyone. I'm just answering questions.
