speedo gear
my speed has changed 3mph when i changed my wheels and tires over. I expected that. My question is where do i buy a new speedo gear and how involved is changing it? I have a 86 5.0 with a aod tranny. At 2000 rpm i am doing 78 according to my gps. I switched to 235 85 16 tires. Also how can i figure my rear gears from that info? Thanks
