In Need Of Some 8 3/4 Technical Info

I believe these axles are small bolt pattern, they measure 4.25" cl to cl. I will be doing the narrowing so the cost is not that much.
Since I just spent two days cleaning this thing up and its squeaky clean and detailed how much could it bring???

You don't measure from center to center of the studs to get the bolt pattern size. You measure from the center of one stud to the outside of the other to get the size. I don't know why the companies did it that way but they did. If you measured center to center and came up with 4.25" that's gotta be the bbp cause the stud is 1/2" and half of that is 1/4". Add 1/4" to 4.25" you measured and you got 4.5". Also note 4.25" stud centers was never used by Mopar anyway. Small pattern is 4" and big pattern is 4.5". Also for future reference if it was a 65 rearend it'd have bolt on brake drums. Not slip on drums. Real pain in the butt to work with cause you usually need the special puller to get the drums off.
