Can't seem to find speedo calibration info...

[90_K5 Blazer]

Hey guys,

Anyone know off hand if a 1990 k5 would just need a speedo gear swapped to offset for bigger tires - like most old gm's? Or do you need to get an electrical box since 90's have electronic speedos?

Thanks again,

Hopefully all the links work still:
