Cv driveshaft lengths
 

We are putting a 3-4 inch lift on my friends jeep with an sye and we have to place an order for his driveshaft. I know your supposed to put the sye on and then measure what length you need but it is his daily driver and we want to finish it in one weekend. I was wondering if anybody had measurements and if it varies that much from a 3 - 4 inch lift?
