The plastic dipstick handle on a 1997 33 liter was broken by a dipstick at the garage you can still see the yellow plastic half inside the metal collar Any bright ideas about how to get it out without?

Take this back to the dipstick at the garage. Its their responsibilty to fix it if they broke it. You will have to take the tube off the motor and replace it. But I would take it back and get firm with these guys. Sometime you can get a magnetic wand for a buck or two and pull it up or maybe a pari of needle nose pliiyers and goto a junkyard and get a different one
