That’s not true, I just bought a new balancer from BHJ and they carry a early 68,69 version with the scribed lines on the passenger side with the keyway located at approximately the 1-2 o’clock position. There are also scribed lines on the opposite side of the keyway also, I presume possible for 70 and later. There are no numbers just lines so you can leave it like it is or add some numbers or a tape to it. Here is the invoice with the information on it. It’s best to actually go to their website and look at it and always call them before ordering. I called them on Thursday and they made it and shipped it out on Monday, I thought that was quick.
