Hi Dan,

It was near the top right of the cover, found it when i was prepping to paint the cover. I don't know if this a normal stamp or not, maybe someone with more knowledge could shed some light on this.

I have 2 rear ends for a javelin. one is a 73 rear with an "A" on the flat case and the other is a 71 rear with a "O" on the flat of the case. what ratio are these? I plan to use a mopar rearend or a ford 9 inch as these amc rear ends are really weak looking. Small axle tubes weak 2 part hubs and 40+ years is too much for me. Steve in Ga.

Mchaggis, the Aussie Javelin diff should be 2.87 ratio LSD, that's all we got here as far as I know. With changing the gears, you will be fine, what nobody has mentioned is that Jeep didn't run the 2.87 gears, so their cut-off ratio is higher, something like 3.08 or 3.15 not really sure on this but the guys selling the gears usually work with Jeeps rather than AMC cars so sometimes it can be a bit misleading as to what fits.
 
Maybe an option for you, I got some 3.54 gears out of a Jeep axle (CJ7 I think) to put in my Aussie 69 Javelin, installed without any issues but no good if you want 3.73s.

Edit;

rookie error,

I replied to what was on the first page without noticing the date, or the other 7 pages of replies

:facepalm: Smile


So its probably been answered 10 tires already and the thread has gone in a whole different direction by now



[The twin grip pics above are all of the earlier two piece, 4 pinion "Power Lok" type, used till around 1971.

Since his is later it would be a Trak-loc one piece 2 pinion type.

IIRC, the later 1piece LSD had a more boxed out appearance, more squared off than the standard, open carrier.


To the original poster,

if you coupe get a picture with the carrier rotated a bit, so you can see the open window, it would be easier to tell.]
