There are a number of articles on the replacement of these components and suggested sequences. One is in the "How to Hot-Rod a Tri-Five Chevy" book, (I'm sure that is not the actual title), Also Tom Brunnell's (sp?), book on "How to Restore Your Chevrolet Truck" (again not sure the title is accurate), has a section on those repairs. Lastly, a number of magazines have run articles on this sequence of repairs, Rod & Custom about a year ago being the most recent I can remember.
