Who out there is running a 4l80e and 9"? What lenght driveshaft are you using? Where did you get your yoke from? Car is a 1999 Trans Am. Thanks for the help

 

The driveshaft in my car was used with a 4L80e...I have to get the diff worked on. If I end up doing it myself I'll measure it for you.

 

just take the time to squeeze under the car and measure it. I ended up having to do this in bad weather as all my other toys that can get stolen easily are in the garage. My measurements with the 4L80 and the stock 10 bolt was the same as what Bob has for his driveshafts. I haven't tried it yet as I am waiting on my center section to get finished...still. Oh yeh make sure you count the splines of the trans tail shaft and see if it is threaded and be sure that you have the car sitting in the air as it would on the ground to get the correct measurements.

 

Thanks for the info....With so many people running this common set up there should be a known length. Maybe the driveshaft manufactures would know.

 

there is a common length but it could vary with how you car is set up. So to get the most accurate measurement it's best to put the car up on ramps and measure yourself
