Call Joel at Allstate Driveshaft in Yucca Valley, CA (760) 228-1127

Why are you going aluminum?

Dart/Scamp with a 904/8.75 set up should be right at 51"

Thanks why not aluminum? I thought because of the less weight and i think its a good one, or would you prefer a steel one?

Aluminum has a fatigue cycle life.

Ok good thx for letting me knew, then i will not use an aluminum driveshaft

Then you need to measure.

51.96" is what the service manual calls for with 904 and 8.75 rear.

Thanks with the large or with the small pinion yoke?

crackedback,

Another drive drive shaft. We are moving to an a727 /8 3/4 from a /6 902/7 1/4 i think. I was told to cut 2.25 inches off of it.

Good or bad info ?

Thanks
Ian.
