I bought an NOS sure-grip differential on eBay for my kid's Duster. These are from a lot of old stock and loose and unboxed, therefore no part number. However,they are marked on the case with the number 18-05-039-903. Please tell me this is the correct size case for 3.21 and lower gear ratios! The price was too good to pass up, so I jumped prior to researching it.
We're thinking of dropping in 3.55 or 3.90's. I hope this will work.
