Resetting odometer on 80-86 mechanical speedometer?

Resetting odometer on 80-86 mechanical speedometer?
I found a decent trip speedometer at the junkyard today, but the total mileage odometer (not the trip odometer) reads around 10,000 miles higher (~77K) than my current speedometer (about to hit 64K). Is there any way I can reset or adjust the new speedometer to read the correct mileage?
If not, I could always just make a note of both mileages and do a little math to keep tabs on my actual mileage.

Kirby...not the easiest thing in the world to do, but it can be done. There's a pin that slides through the odomoter assembly that holds both the number dial and the cams. Basically you need to retract the pin just far enough so you can lift the dials up just enouhg to turn them, set what you want, and slide everything back in place. To get the mileage correct, figure out the numbers 180 degrees out from what you want, because that's the side you can see. Gently slide everything back together and hope it aligns. It may take several attempts to get it right.

Thanks for the quick replies.
It's been years since I've seen the back of this style of speedometer. Do I use pliers or some other tool to retract the pin? And the first idea about swapping out the whole odometer assembly, is that less likely to risk damaging the "new" speedometer?
I'm willing to do the work, but I sure hope I won't damage it. It's pretty darn nice. The needle isn't faded much if it all, plus that trip odometer is a plus.

If I remember right, it will push through....its got a pointed, fluted end on it. I pushed it through with a small flat screwdriver. Also, during the dissassembly make note of the needle position, but to make sure mine was put back on correctly, I took the truck for a ride without the plastic cover in place, and using a GPS, adjusted the needle position until it ran right.
As far as swapping the odometers, the trip odometer type is different from the non-trip type.

These trucks are exempt on mileage anyways,they'd never know the difference in Florida,since we don't have inspections.

and if it was illegal to change a replacement odometer to match what the truck actually has, and the new one shows 40k lower, I doubt that the "legal" course would be to just leave it, cause that would be the same as setting it back! and the point about i breaking, its ot like they can say "youre never allowed to change your instrument cluster", otherwise they wouldve made it a whole lot harder to pull off :P
