Hi guys, I could use some help with my speedo problem. I have a 700R4/208 in my '83 blazer with 4.88 gears and 36" tires. My problem is my speedo reads really fast. Does any body know the PN/color code of the "slowest" speedo gears? I went to my Chevy dealer and all they could tell me was that those axles(14FF&D44) never came under a Blazer and they never came with 4.88 gears. I already have a reduction box on the Transfer case and it helps a little. Any help?
