9.25 Question

[wcwilliam]

I have a 73 Charger with an 8 1/4 rear end and had a buddy give me a sure grip 9.25. The rear end is in perfect working order when we pulled it, but there seems a lot of mis information about the 9.25. It looks like a lot of people get it confused with the dana 60. But my question is, how were the 9.25's stamped? I mean it looks like they were in production for quite a few years and I can find only 3 different sets of casting numbers for all 9.25's that were produced. I measured it out and checked, and the 9 1/4 will slide right in so thats not the problem. I dont have any hang ups really, but is there any way to tell what the 9.25 origionally came out of? Or even what year it is? This question is more for curosity's sake, so i figured you guys may know.
Casting numbers;
Bottom center: 295
Bottom Right: 23258
Top Left 3723199

Will any of these numbers give me a clue as to what year it is? Like I said though, I'm sure its a 9 1/4 because of the 3723199, but not the year. It came out of a 74 charger, But who knows what before that.

If it's all original with factory gears there may be a date on the ring gear. Other than that I suppose you can take the width measurements and eliminate what it won't fit in.

I don't really understand the question. Why does it matter?

There is a date on the ring gear and the ratio. Look in my Roadrunner restoration thread last page. I have some pictures posted there of a 9.25 sure grip with 3.55 ring gear that came out of 1975 Chrysler C body according to the guy that gave it to me for free. The one that I have is a 1/2" wider spring mounts than a 8 3/4 B body perches and is approx. 2" longer overall I believe. I could be wrong but I could measure and give you an exact overall length or width rather.

Well if I get a chance this weekend I will check for the casting number this weekend on the 9.25 in my 74 Charger which came from the factory with it.

Additionally if it came from a 74 charger it will go into the 73 as the measurements and ISO mounts are the same.

Oh and I dont know how a Dana 60 and a Spicer 9.25 can be confused as the covers are completely different shapes :edgy:

People who are not familiar with the 60 often make that mistake...

Are they still making them?

Pretty sure they were in production at least until 2003.

Not sure...been years since looking under a newer truck but I think the 04 Dakota was the last one to use them....
