I didn't do it the way the youtube guy did it, using dimensions. I did it by cross-referencing the correct seal from other GM rack kits, because the rack is obviously a GM (or GM-derived) rack. The system's design (especially the 8v pump) screams Saginaw, through and through. In fact, I believe the threads and fittings on the thing are even in inches.
First, I bought Edelmann 8740, the "cheap" one, which is sold under other brands such as Gates and AutoZone's house brand.
The bottom pinion seal I took out of my original rack had the number 26005161 on it. The new seal from Edelmann 8740 was smaller - the trouble everyone faces. So I cross-referenced 26005161 and got "Opel Corsa, Sintra" on a part number list. GM vehicles for sure, but not US market. Still, knowing how GM builds foreign-market vehicles from its domestic-market parts bin, I looked for a rack seal kit for the Corsa and Sintra. Easy enough to find, but hard to get in the USA. More searching ensued. On a Russian website for Russian enthusiasts of American muscle cars, the same kit was listed for Corsa and Sintra as for a '94 Firebird Trans Am. Bingo. This is Edelmann 8785.
The added benefit of getting Edelmann 8785 is that you can get a bunch of extra parts, some of which will also fit the rack, so you can use them as backups. It also includes the little white plastic sleeve collar thingy that goes inside the pinion chamber, which will also be a different size than the one in the Edelmann 8740 kit. Usually this does not need replacing.
That youtube guy doesn't seem to be a very good rack rebuilder. I haven't watched his other videos, but perhaps he has bitten off more than he can chew. I bet your analysis is correct, that the pinion tension isn't high enough.
