xwroo 348 Posted October 29, 2015 Hi all, after some info on my xw trans and diff. On the id plate under trans its got a 'R' is that a c4? What type of diff do I have the tag reads like this... Part No ARC9DW4005 C Ratio 2.93 Ser No 012956 The tag is pretty hard to read but I think that is correct. Thanks for any help Share this post Link to post Share on other sites
