Yep, sounds like an open diff as mentioned above. Tires will spin the same direction (in the air) with a limited slip. ANd with 4.88s and 33s you'll be close on the speedo and odo. On my '85, I find the odo is just about right (maybe 1% off) but the speedo is about 8% slow. So I need to have it indicate 70 to get an actual speed (via GPS) of 65. With 35s, the speedo is just about correct, but the odo is off. All depends on how yours are calibrated.
