Thanks for more great answers! The problem I was having was freeing the parts from the bolts that had rusted to the steering pieces. The nuts came off with no problem. Following all the advice above, I heated the parts gingerly, used the penetrating oil as suggested and after banging away on them I was relieved when they actually came apart! Now onto getting the kingpins out. I am reading the past threads about that subject.

'49 3100 "Sweet Caroline" because the truck has fabulous curves .... like Caroline!
