Happy Easter Florida members.
So I was checking the 9 inch that was installed PO in my 53' F100 and noticed the axle flanges had multiple holes drilled in it. Besides the 5 already used by the studs there are another 10 holes. Also the drive shaft is running on an angle to the center section. The axle housing is not tapered and appears to the the large bearing type. I will not be racing the truck and would like the drive shaft to run straight down.the center of the truck but am opting to install a posi unit
I am running a BB 429
