Looking to decode this 9in rear axle. I seen a few examples online, but nothing that fits this exact format.

C2AA4001 DV 100
3.00 1LD
I assume the 3.00 is the gear ratio, but the rest I'm uncertain of. Also, the third member has this exnsion housing with a bump stop I've never seen before. Anyone seen this?
It does describe a 3.00 gear ratio, from a 62 Ford with an assembly date of 4th week of November, 1961. Over the years Ford played with different pinion snubber bumpers, on the diff, on the body, none at all, etc.
C2AA4001 is indicative of a 1960's vintage Ford Passenger base.
The 3.00 is the ratio as you suspect.
1LD is likely the build date in the 4th week of November 1961.
Edit: Looks like I was beaten to the punch as I was digging deeper to see if I could find anything further.

Many thanks sir! Im looking to convert to disc brakes and I needed to ensure this wasn't a truck or 50s axle.
No real need for disc brakes on the rear , 75% of braking comes from the front brakes .
And on a pickup with not much weight in the rear it's a waste of time .
X2. JMO but my issue with converting to disc on the rear in this and many other cases is the mishmash of parts. Some have you using GM parts, some old Ford Grandad parts. Great when YOU read the rightup and make the installation.
What if you need it worked on when you're not around?
Also, the parking brake feature on most of these is very weak.
Putting bigger drums on might be a better idea, but usually the stockers with decent shoes and properly adjusted are just fine.

Since you mentioned the mishmash of conversion parts, when working on my 51 F1 with a CPP front disk brake conversion, I found out that the calipers are from a mid 70’s C-10, the rotors from a mid 70’s F100. And that one of the stock bearings on the F100 rotor has to be replaced with a different size (forgot if it’s the inner or outer). The good news is the tech from CPP was very helpful in identifying exactly what I needed.
