Duh!! I remember what you mean now. Don't know what I was thinking. Like Daredevil, I have one for a cone type sure-grip which is what's usually in a 489 case.

I have the 489 type. The others use a button I believe.

There's got to be lots out there. Most that went with the Green bearings needed to remove it. Maybe do a search in this forum http://www.forabodiesonly.com/mopar/forumdisplay.php?f=34, you will likely find one there.

Good Luck.

I think the "657" was just an early version(first 8 3/4?) of the "741". It was a small pinion like the "741". I think they were made until 1964. Someone with an early "A" may be able to tell you more.

do i have to disassemble anything on the center chunk to install a new block?

Yes the 657 is the earlier version of the 741, they're identical. As far as which type of """"SURE GRIP"""" is in the unit, how about you tell us cuss it could be either cone of clutch. If it is a clutch type there are 2 thrust spacers that can installed without disassembling the entire diff case.
