So I've had this 1965 Chevrolet C60 school bus since 1993-and for most of that time, the steering drag link has been getting progressively looser and more sketchy. I've been searching for one of these, for decades. I've long since memorized the number-Moog DS900.
There's pretty much no mention of it on the internet. eBay is of zero assistance. I've spent dozens of hours chasing a rumored batch of these that someone made and of which an example would set you back $400. I was ready to just pay the $400 at this point, because if you've got one of these rigs with the 7000lb front axle and the old, smaller stud size drag link then you know how difficult, err I mean impossible, it is to find a new link.
Well it turns out that I should have just called Rare Parts, like 15 years ago. I got a suspension rebuild kit from them back in the day for my 1961 Pontiac Tempest, so I'd used them before. They have seventy three of these arms in stock. Here's the link:

So this decades long problem that I've been tolerating is now solved-and the solution was cheap :-D Now they only have 71 of these in stock, because I bought two of 'em
