I thought the casting numbers on the boxes are the same but the stamp is what told you what it is

The sticker on the box tells you all you need to know, but most of those are gone.

Here is a good write up http://www.hotrod.com/articles/ccrp-0901-gm-steering-box-upgrade/

Most circle track guys (in the stock clip classes) that dont want to spend big money on an aftermarket box go on about "camaro boxes" but there is at least 2 better options. F41 and Impala SS

If your current box is a 605 series box and not an 800 series unit, you'll need a pitman arm.

Yeah if you have a 605 get rid of that POS

A 600 box (not to be confused with the 605) is the pinnacle of saginaw boxes.
Turn one deals primarily with these.

The thing about buying a box these days,where they're rem'd and not new there's a chance you're getting stuck with a standard ratio box that was once a core.
I bought my box from gm way back,I'll l see if i still have the slip for it tonight

There was also an article in Hot Rod some years ago. They mentioned using a steering box from a Jeep Grand Cherokee. I'll see if I can refer back to that article for more info. Either way, you'll still need to replace that pitman arm.
If I recall, it's also a quick ratio box.

I found it. They mention using the '96-'98 Jeep Grand Cherokee box. It has the 12.7:1 ratio and is the 800 series box.
So, I'm thinking that it may be easier to source one of these from the junkyard than one from a Monte SS. GN, TA, T-Type, 442, H/O. Z-28, etc. Plus it's probably a newer box with "hopefully" less wear and tear on it....but that's a crapshoot.
