Has anyone had an issue getting the correct carrier shims? I ordered Ratech's installation kit to install an Eaton posi and 3.73 ratio gear set. The shims provided were (4) .100"/plus shims and an assortment of .010"-.020" shims. The way these were designed was to sandwich the smaller shims between 2 larger shims for over .200" of shimming. The shims I removed from the original carrier were .078" and .080" and it looks close to what I need for the new carrier. Ratech claims I have a carrier out of a Corvette. The factory service manual shows shims ranging from .064" to .094" so I think it's a cataloging issue. I can't believe they've never run across this before. What's up!!!!
