Thanks for the input.  I'll have to try this with my factory speedo.

The accuracy is right on the money when compared to my GPS unit. When I change 
tire sizes in the future, I will have to change the speedometer gear. Since I 
have a 350 installed, that is easy. I don't know how far back GMs speedometer 
gears will interchange. I worked in an independent garage in the 70s, we kept a 
box of them to pick and choose from, it seems that all of GM speedometer gears 
would interchange, you just had to get the right number of teeth to make the 
speedometer read correctly.

Jim,
I hadn't thought of trying this. Any issues with accuracy?

When I replaced the speedometer in my 1950 Chevy, I used the workings from a 
1974 Chevy truck. Making it fit the faceplate and the speedometer housing was 
almost like it was made for it. I suspect that most of General Motors 
speedometers are very similar and will interchange without major modification. 
Once you get into the 90's where lots of stuff was made in countries other than 
USA, all bets are off. You should be able to find an instrument cluster from an 
older truck at a junkyard fairly cheap.

the speedo on my 59 reads fast under 30, hangs at 30 from 30 to 45 and then
reads slow over 45.
is the speedo on my 59 worth rebuilding or should i just buy a new one?
lmc has a new speedo for the 55-59 trucks for $150.
has anyone bought a lmc speedo?
