I had mine installed in 1.5 hours on my back on a pair of plastic oil change ramps. I did need an extra set of hands actually getting the Hurst into place (I was under the car and someone else guided it down from inside the car. Other than that it was much easier than the under drive pullies, that I put i about 2 years ago. Very easy DIY project in the drive way and I didn't take my drive shaft out, but I will be in 2 weeks when I get my Spyder Shaft!!
