Is your 40 from South America? Based on Mark's observation, he thought 73 or older. If it's from SA it very well could be a hodge podge as you say.So, this looks like the part I am in search of. I'm just uncertain of the exact part for my model year. The truck is a 1982, but who knows it certain parts were hodge-podged together. The transfer case on the truck, was clearly replaced. It looks quite new in comparison to the original engine/transmission.

46000-2, STUD, PARKING BRAKE DRUM, FJ40 1974-8007 Order HereThe 3 speed Parking Brake Drum Studs are discontinued however, this Stud can be used for the 3 speed also. On some models you may have to open the drive shaft flange holes slightly larger to accept the larger 4 speed stud. You willtpi4x4.com
Either way, you have to remove it. Maybe a 2 banana job. Then you can measure the stud and hole to what year will fit. As TPI's site says, you could use the newer stud on an older drum, but have to open the holes. Best to figure out what you have first.
