It's on a 1964 belevedere slant 6

something doesn't look right to me. Can you take a few more pictures of the rear axle and show more of it.

1-3/8" small stem pinion (aka. '741')>
Carrier casting numbers: 1820657 (1957-1964), 2070741 (1964-1972). This assembly was typically used in low weight/low horsepower applications through low weight/medium horsepower and high weight/low horsepower applications. Pinion depth and bearing preload is set with shims. Differential bearing setting (ie. backlash ) is set with threaded adjusters.

Number is on the other side, they are big, and you go by the last 3 digits, ie, 741, 742 or 489.

I know it's supposed to be a big casting number on the left side, but mine seems to be flat,

Clean all the way up to the support rib. Sometimes the numbers are extremely faint.

By looking at the picture and reading what the car came with I'd say it's the small guy 741

I think i just understand, the number on passenger side is 1820657. So it's a 741

I think like 63 dodge, Plymouth, before the 741 casting. I am pretty sure that was what was in my 63 Dodge 330 from the factory. I also think the sure grip in the early 8 3/4 were slightly different as well. It would be a small pinion. 1957 to 1964

I was gonna' ask- what's it on, and what'd it come off of?

Real early, maybe?

Per his original post (easy to miss at bottom): 64 Belvedere /6

'58-'64 c body 8 3/4. Uses 1 3/8" pinion so similar to a 741 but the earlier version (657)
