Instrument panel on 90 'Burb

[Frozen1010]

Hello,

I have a 1990 R1500 Chevy Burb, and I am considering doing a custom instrument panel. I have read that there are two types of Spedometers, one that has a mechanical cable and one that is electronic. I have not taken the dash apart yet to see what I have, but if it has the mechanical type, is it possible to convert to an electronic type? Dealing with an electronic signal is way easier than a mechanical one and doing the conversion.

Thanks,

Lou
