Footnote...
I had to pull my front diff last summer because of a broken gasket. The new factory gasket is a steel shim with fiber faces bonded to it, kinda like the oil drain plug gasket but the steel shim is much thinner. That will solve the cracking seen with previous versions. I installed...
Put an 8mm bolt in the end of the birf (as a handle) and push-pull the birf to see how much in and out play you have. If it moves much more than the width of the snap ring notch you have a long birf and a short flange. That allows excessive play.
R DOT appears on factory replacement parts that would have originally had the VIN attached to them. Original heads had VIN plates on them.
You will see this on other replacement parts that were originally marked. Such as fenders, hoods and doors.
This is Ellie, the protector of my wiring harnesses. She was an abandoned feral kitten that my wife found under our cabin whe she was about 7 weeks old. She is my best buddy.
My wife's sunroof was found to be inoperative and we needed to get it open to check the sunroof pan drains. I opened it up and found a mouse-chewed wire in the harness right next to the motor. I don't know how the sonofabitch even got up there :bang:
Is that a JDM truck? If not, which market?
EDIT:
I went back to the first of this thread. That is most likely a distributor-sourced local accessory. Much like the platform hitches sold here in the US.
