Hi All

I Have two rear axils to choose from

1 has the Identifection marks T15 73AG4025CA and has a small flange roughly 70mm pcd 4 bolt holes

the second has T19 93AG4025CA and this one has a larger propshaft flange roughly 90mm pcd 4 bolt holes

can any one tell me what are the dirrences, are the diffs the same ratio or are they differant

dont know which one to fit

What type of axle [ make ] are they ? Sierra ?
Are the numbers stamped on a alloy tag or on the diff casting ?
If you look in my photo archives there is a section about sierra diffs
