Your 1st problem is Haynes crap books. Worse when use a PDF copy of very old version of Fiero book. All Haynes versions for all vehicles have big problems. Chilton isn't much better.
Even in the '70's Many OE and Aftermarket Rod ends and BJ don't have grease fittings. Don't even have plugged holes to install them.
In Fiero Front...
At Best you have 1 for each BJ and Rod end total 6. 4 for rear.
Many replace 1 or more joints that don't have them.
Moog and some replacements have grease fittings and easy to find them.

Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
