Just a quick note on application listings in our catalog.  GM changed their fullsize trucks to independent front suspension in the 1988 model year.  The Blazer (K5), Suburban, and heavy duties such as crew cabs and cab and chassis trucks kept the straight axle until the 1992 model year when everything from GM became IFS.  Most of our parts are exactly the same for all of the straight axle trucks.  If it's listed for a "'73 to '87 ('91)" this indicates that it fits up to '91 on the straight axle vehicles.  That's part of the beauty of the GM straight axles, they're very interchangeable for nearly 20 model years!
