I believe the sway bar should have a little nipple on it straight out on the tip of the sway bar ends. That's the fat F41 bar.
Did you check the carb number yet? Here's a pic of one of the ones I had in the shop showing that 5 over stamp. It was date-code stamped 1574, which is the 157th day of 1984 (a leap year). After the 1984 production run. That means it was made June 5th, 1984. A Tuesday. The JCY was overstamped as well on the 84 carb.
