New guy here

Hi all.

I've always owned 60s GM muscle cars, until the last several years when I bought a 1964 Austin Healey 3000 and an 80s Honda which I race in the local autocross. The only Ford I've owned was my 1994 Escort daily, which I'd still be driving today had we not needed a larger car when we had kids.

But, I'm first and foremost a car guy, and I appreciate just about anything with four wheels. I love cars.

A few years ago, our oldest started school. We long ago knew we would be sending them to a private school (you don't send your kids to public schools in Memphis if you can even remotely afford not to). In order to maintain my expensive car hobbies (racing, and I'm also currently restoring a 69 Chevelle convertible) I started selling on Ebay again. I've been selling off and on since 1997 and it's made me a lot of money in the past (I built the garage/shop at my first house with Ebay money).

I sell mostly anything I can get my hands on but I naturally gravitate toward car parts. Last summer I purchased about 10 van loads of mostly NOS old Ford parts 1928-1980s with most falling in the 1930s-1960s.

Now, I'm not trying to advertise, so I'm not going to post a link to our store. Rather, I'd like to ask for assistance from time to time. While I love old cars, old Fords are not my strong suit. I've learned a lot in the last year, but I still scratch my head a lot, and people ask me questions that I cannot answer easily. Also, I make errors in listings sometimes because I often have nothing to go by except the part number on the box, and the part inside the box is sometimes not that part. And I HATE sending someone the wrong part. I have some parts books, but mostly for trucks, and they're incomplete.

Here's one, for instance.

The box says differential carrier assembly, part number 1A-4017. Cast into the assembly is 1A-4025.

I THINK it decodes to 1949-1954 Ford, but that's based on what's on the box. I can't find anything on the 1A-4025.

I had a question from someone, asking if it would fit a 1954 Mercury. That one was way out of my league. My hunch is no, but I don't have access to a Hollander book, so I can't. Might not be a bad idea to pick on up, I do get asked these questions from time to time.

So, anyway, hello from Memphis, and any help you can provide would be greatly appreciated.

You generally will not find casting numbers in Ford parts catalogs. They are cataloged by the part number. Sometimes the listing might include a casting number.
 
part #1A-4025 is not shown in the 1954 Mercury parts book, so I would say no. If you need help with any 49-55 Lincoln Mercury part #s, let me know and I'll be glad to help. You can PM me.
 
...The box says differential carrier assembly, part number 1A-4017. Cast into the assembly is 1A-4025...

Andy, no help on the example itself, but a bit of an education on the Ford system of parts identification: The carrier in your example has a part number cast in, which identifies only the carrier itself. The assembly number identifies the group of related parts that make up the complete assembly, each part having its own number, as the carrier has.
 
Thanks for the help. Sometimes these old parts make me crazy.

This illustrates the problem I sometimes run into, which is a part in a box but no indication if the part is actually the one that is supposed to be in that box.

So the assembly includes the casting, end caps, and nuts, I would guess. Plus the bearing races.

Now I can appear to not be a total dolt to all of Ebay, at least with this item :)
 
Andy, just an opinion, but I think you'd be correct in that assumption. If the box said differential assembly, then that would be all inclusive, but it said carrier assembly, so that makes sense to me.
