do you mean you want to put an electronic speedo in the hole the original speedo was in? would probably start by some searching to see if you can find one that's the same diameter and then see how it mounts and if it might be adaptable - if you mean put the electronic guts behind the original face, that'd be a DIY project that won't be simple, considering the calibration of the new one likely wouldn't match the original numbering
