E-berg said of the 9.25 rear:

"In a New York minute: I'd put in a stock Chrysler 9.25" axle from a later
Dak. Trouble free, strong, cheap parts, super-easy to service. And WAY
stronger than any of that FoMoCo or GrandMother garbage.
While not as strong as the Dana 60, it's quite a bit stronger
than the 8-3/4", lots cheaper and easier to find, and only slightly heavier.
The currently available Sure-Grip is even the Spicer clutch type!
Another plus is that it's a super-easy rear to work on. The
externally-adjustable backlash and diff bearing preload is a wonderful
thing! And the crush spacer is beefy, eliminating the occasional failed
spacer syndrome seen in #489 8-3/4" axles, while making pinion setup a snap."


On one of the Dodge truck forums about rebuilding the 9 1/4 rear:

"If you throw the pinion in the
freezer for a couple of hours you should be able to pull the inner
pinion bearings off with no problems! and if you put the new pinion
bearings on the stove for a couple min. it will fall right on your
pinion! and the best thing is you dont have to pay anyone to do it!"

This might be a good value:

Well, I'll have you know I got great news today.  The rear end guru had to reshim the pinion and I was good to go.  Other than that, he said my work was excellent! 
I'm so giddy with happiness right now trhat I have to do the Stanley Dance...

See, you didn't mess anything up too bad, and a lack of a shim is not that big a deal. Trial and error is on the list of requirements of rebuilding each and every single rear end, so no harm, no fowl, the teeth were just meshing a little bit too far out on the ring gear, so not too bad.

What a difference the 3.55's have made.
Gas mileage aside, I'm now ready to go shock some RoadRunner owners....

My dad had a 74 Fury III that he special ordered with a BB and low rear gears for towing. Heand my mom picked it up at the Windsor plant as it came off of the line. Anyway, I recall racing some "fast" cars with it in highschool and it ate up many of them in the 1/4 mile. You should have heard the lame excuses my buddys came up with when they lost to the big family car! Big block B Body+low gears=traction+good acceleration. I miss that car!
 
Good luck with your new toy! Let us know if you take any hot rods down! lol

I knew you could do it, Stan.  Never doubted for a second.  Nice to get some positive feedback from the pro, too.  Now drive the wheels offa that car!
