speedo acuracy after conversion: 1968 /6 to an 83 318

Hello All,

got a question for the experts. I've just acquired an 83 5th ave (M-body) donor for my 68 dart. now in 68 the speedo was in miles per hour, but up here in Canada some genious changed us over to metric, kilometers per hour back in 1975. How is this going to affect my speedo when I go from the /6 trans to the A904 that's on this 318

Do I need to change some kind of gear ratio somewhere?

Also, will the driveshaft from the 318 fit the 7 1/4 rear from the slant six?

any advice would be helpful, thanks
