They could be 2.76 or 2.91's or maybe he meant 3.73's,regardless $400 for the whole rear is a deal and a bolt in big advantage for you and its MOPAR...buy it put it in and if you dont like the gears you can always change them out,should be a tag on 3rd member identifying the ratio[may be missing ] but will be stamped on the ring gear the ratio it is if factory set up,the 741 will last you forever with your set-up[providing its in good working order ] and with tons af room to improve upon it should you 'beef up your combo' in future...if it's a complete rear-end for 400 bucs I wouldnt think about it too long or it will be gone...and if its local even better,you will need to get new u-bolts[2 pairs] and hopefully it comes with or he has the shockplates to match rear-end....good luck
