Re: BE axle Posi unit...
I guess I'm confused. Colvin's book says that a posi with gearing of 3.90:1 and up was an Eaton 4-series, with no mention of anything special for COPO's (p.303). This was the casting that I attached before. Cunneen makes no mention of the carrier guts being special. Attached is a photo of the inside of my carrier. It came out of my BE rear end. It is quite possable that it was swaped out sometime in the past, but I have no history of the car prior to 1989.
Thanks for your help, as I am now as curious as Mark.
Andy
