Apparently you can use 8.75/Dana adjustable bearings with custom tubes also. '72 Scamp, 3500#, 440, S400, blowthrough, meth. inj. 9.78 @ 139 so far at 12 psi, 11.00 @ 131 on real street tires.

Wonder why the retube it.

Wonder why the retube it. I've been running my 9 1/4 for about 5 years now with no problems ( mid 11 second car ). Heard all the "C" clip horror stories - and maybe some are true . Obviously thats a drawback to using that diff ( along with the fact that they don't make a spool for it ). Otherwise, it's a very strong diff and would easily handle a 10 second car IMO. Just seems to me that the cost to have it modified for bearing retained axles would be more than just switching to a Dana or a Ford 9"? I'm in the process of updating my drive shaft to use 1350 joints ( replacing the existing 7260 joints - which have also been trouble free for 5 years )and gotta make a diff decision. Fastest 300

Just bought a 1350 u-joint size 9 1/4" pinion yoke from him to upgrade my driveshaft. I'm might by the upgraded "C" clip axles from him also. Wish they made a spool for it. I'm presently running a detroit locker in mine - and I don't like it much. Car does "odd" burnouts at times - like both sides aren't locked in. Car launches ok though ( both sides locked ). The locker is new and I had it checked out - it's in good working order. I also have a spicer clutch style sure grip that I had rebuilt extra tight. I might put that back in. Fastest 300

My friend ran one for years in his bracket Stude (SBM powered) with good results. Recently put a Dana in it but would have stayed with the 9 1/4 if a spool was available. 7196382-hoodspring235.jpg (34 downloads) Last edited by goldmember; 05/07/12 08:25 PM.

A spool and some pro gears would make that thing a pretty nice unit and cheaper than a 9" and lighter than a Dana.
