: Yes, you do have to consider the differential yoke length and size. But it is far cheaper to buy the Motorsport driveshaft than to have one cut, new yokes welded, and having it balanced. The driveshaft from FoMoCo is the right length, balanced and ready to go. Plus, there was an article in one of the magazines that showed that the lower mass of an aluminum driveshaft was good for at least .1 second in the 1/4 mile. Rotating mass is equal to about 1 1/2 times a non-rotating weight in your car.
: : and very important also, is trying to find some that will work on/balance a alunimum driveshaft. It's a different metal then steel and takes different methods: most driveshaft shops won't touch alunimum and it has to be welded up when you get it. say with a steel one. easier and cheaper

: : There are several types of rearend yokes, especially for 9" rearends, they can vary as much as an inch in length, so be sure to get your setup together and measure before ordering an expensive driveshaft..

: : : : I was looking at the Motorsports catalog one day and saw that the aluminum driveshaft for late model Mustangs was the correct length for a Maverick with a four speed and 9 inch nodular housing. For the cost of having a driveshaft made up, you can get a HP aluminum one from FoMoCo. Only thing you have to change is the U-joint in the rear.
