Rear end help

[Leroy-B1]

So I bought a rear end from a local guy and he wasn't sure if it was a 68, 69, or a 70....The problem I have is I want to order the 5 lug conversion axle kit and not sure which one to get.. The brake drums are off and I am measuring from square flange on end of tube to the same on other side and the measurement I am getting is right around 56.25 inches from square flange to square flange...if I measure from backing plate lip to other backing plate lip its right at 55 inches...Can anyone help me? The kits are 63-69 and then 70 only...don't want to order the wrong one. Looked at old threads and didn't get a lot of helpful info that I understood...lol

Thanks in advance.

(Backing plate to backing plate measurements)
If you are still unsure pull an axle and measure.

Quote:
axle width is 55.5 wide with 30.5 long axles on the narrow rear end. earlier rear end

axle width is 57 wide with 31 5/16 long axles on the wider rear end. later rear end

ok...think mine is an newer one...will most likely have to pull an axle if I can find time

Trying to save some time by not taking it apart at the moment...I'm a school teacher and in grad school and both my sons play travel baseball, don't have a lot of free time for a couple of weeks to do it and wanted it to be here for when I am free....Its going under a 60 apache I'm changing the suspension on.
