This Drive shaft is praticaly new.It is Dennys Nitrous Ready Chrome molley drive shaft.It has the upgraded yoke and Ujoints.It cost me a total of 515.95 and 55.00 for shiping NEW.I put this on my car and it made one dayno session.I melted a piston.Since pulling the motor I have changed the hole car up and will not be using this drive shaft.This is a great drive shaft.It has a lifetime warrenty and I still have the invoice.I will take 415.00 plus shiping FIRM.My car was a 700R4 tranny and a 9inch rear end.Let me know if you have any questions.The measurement on the driveshaft from center U joint to center U joint is 41 3/4.
