Hey guys I just swapped rear ends from my 3.21 open diff to 3.91 and posi. Do you all know any way to fixed the speedometer to read at least close? It reads about 10-20 mph over. Like I'll be doing 40 and the truck will read 50. Or the truck will be reading 90 and I'll actually be going about 73ish. I'm more worried about how the odometer reads high and putting more miles on the truck than there actually is. Thanks guys any advice will help.

Does a 96 read off of that or the rear abs sensor?

So changing the speedo gear should fix it? And are they fairly easy to change?
