Question
i have read that ford nine inch will work in a duster dart or demon. do you know what the width difference and what mods need to be done to make it work. have a spare around want to make a race car
thanks sheldon

Answer
OK  my quick answer is yes it will work- - in nearly anything, and is a good diff to choose for numerous kinds of racing.

As to exact measurements and various mounting flanges and brackets, there is no way I could help you without seeing the car in person.

All modern rear ends can be modified for width and so forth and there are many shops that specialize in that kind of work.  There are even shops that specialize in the Ford 9" gear.  

Get yourself a subscription to Circle Track and look at advertisers.  I think it's www.circletrack.com .  CT is the best racing mag on the racks, no matter what kind of racing you're interested in. The tech features alone are worth twice the subscription cost.

Good luck

Experience

I have been racing for 20 years, I have been the Central Florida SCCA Regional Championship points for 5 years running, and won the championship in my class 2 times. During my first start in the 60's I won many solo awards and the State Championship Drags. I serve as a senior instructor for SCCA, and have taught in Mercedes AMG events at Daytona, and Dodge Viper Days at Sebring International. I have been in the thick of the competition for all of my career. At one time or another I have driven race cars at speeds nearing 195 MPH. It's quite a ride !
