Quote: A 9" has an extra bearing, it's on the end of the pinion shaft. So there are three bearings on the pinion. A Dana has a big pinion shaft and strong housing that doesn't flex like a 8 3/4 will.
a dana is stronger than an 83/4 but they will flex also.
"As much as this will "irk" the faithful here.....I would NOT put a Dana in a drag radial, small tire car. The housing is too long and too weak. It WILL bend and there is no decent way to brace a Dana housing. Bends the ends forward and not a whole lot you can do about it
