[QUOTE=RalphP;3492992]FINALLY got around to installing the backlit faces on my spare gauge cluster, so I can start rewiring the truck to use a 91-93 tach cluster.
Problem now is a good 1000-1800 RPM motor with a 1/8 drive shaft that can run for about 200 hours non-stop (120 or so if 1800 RPM) to bring the odometer up to my current setting. But it's a start!
(That 1000 RPM behind it as I took this picture warms up too much too fast; it's not designed for 24/7 operation, alas.)

Hey Ralph,
The color of those lights really looks good!
For a motor, an old furnace blower motor would work well..... 1075 rpms, and lots are reversible in direction. They usually have a 1/2 in shaft....
Trying to think of a way to adapt a drill chuck to it. (if nothing is available already)
Last resort, would be to cut it down, and then tap the end to thread into a chuck......
Yeah, I was thinking I could send you a used one..... Wondering of a way to cut the shaft end down enough to use a die, and cut threads so a drill chuck could be attached to the end....... Thinking maybe start motor, and hold a grinder at the side about 1/2 to 3/4 in. in. cut it down to where a die would start on and thread.
By chance, do you know if you can go backwards (odometer)? I have 89xxx miles on my truck, and the dash I purchased has more then 200xxx. Would like to turn it back....
Also, latter on, going to pick your brain about adapting the HEI V8 ignition to the factory dakota tach. The dist. I am running is a aftermarket GM style HEI with a tach plug coming out.
PM the seller; he's done HEI to factory tach before, you just have to remind him the old tach is a 4 cylinder unit.
Got my new 1/4" drive 1000 RPM 12VDC motor, so I'll be setting that up this weekend (have a 1/4-4mm flex coupler; a speedo shaft is .120" or slightly more than 3mm, so I should be good. It'll be a bit off center, but give it 6 inches and it'll work. Might have to bolt the motor down, dunno.)
You may be able to find a 1/2" - 1/8" coupler somewhere, or drill out a smaller one to fit the shaft.
As to reverse - that's actually illegal to do, by federal law. What you CAN do is contact a rebuilder, who does some fancy notary schtuffs to keep their asses out of jail on a rebuild.
But yes, it's supposed to flag if you run it backwards, alas.
Is your speedo a 85, 125, or 110MPH speedo? Should be 125MPH.
I think what happens is the numbers in the odo separate, and leave white lines between them, indicating it has been tampered with. (at least, that's what the gm fellers would do.....)

They sure do make it hard on "us" crooks!!
After I get the motor in, and start that project, I may just see if my orig. speedo. will fit that new cluster.....
Rolling back a speedometer is a Federal offense and you CAN get 10 years and a $10,000 fine. At least that's what a local dealer got back in the 1980's when he messed with a speedometer. Imagine my joy when I got a Federal summons to testify in court about how many miles were on a car I sold. The papers were what they wanted showing how many miles when I sold it.
You can have a unit rebuilt. I had a Mercedes that I asked them to add 200 miles to the unit and that was to make sure every mile the car covered was recorded. I had to send a notorized note with the speedometer saying what I wanted and why. With digital odometers now, it's harder to clock a car. Up to 2000 or so, no so hard.
Well Ill joke around about it...... But in all honesty, (no pun intended) im not worried about it, as long as I can make it work.
The intent of the law, is to keep from taking a high mileage car, rolling it back, and selling it.
I am just trying to match a used odometer to my truck.
My truck has a actual 89xxx miles.
My brother purchased it new, and I know the life of the truck.
