Changed my noisy gears today (from 3:73)for new OEM 3:27 gears won on E-bay for 1 dolla(no one bid against me,LOL)..030 shim and a perfect pattern at 12 thou backlash.Used a pinion spacer with the same thickness as the old crush washer.Treated her to a new traction lok also since my spiders were well wore out.Kinda uneasy about the pink speedo gear though.
