93 model speedometer correction

[bigjames4xl]

After making a rear end change how can the speedometer reading on this model(93)be corrected?

DRAC module aka VSS buffer, located behind the jockey box. I just replaced mine for $75 to adjust for my 31" tires. You'll need the rear axle ratio and the circumference of the tires. Oh and by the way, no returns. If you can't find one locally, I post the name of the company here in Phoenix that makes them up. They are no longer available thru GM.

Good hunting,
