any way to tell what lsd it has or stock?

The first axles (with the narrow bearings) look like SR5 S-code 6.38" AE86 axles ... or T-code (6.7") old Celica axles (they're about 1/2" longer than 6.7" 86 axles... about 27.5")

Non-LSD Zenki 86 axles are about 27" long from the wheel mounting surface. Splines are 24mm. All 6.7" AE86 (disc brake) axles have the huge bearings.

There are some old Celica axles on Ebay here: http://www.ebay.ca/itm/Legend-Dwarf-Toy ... 4e&vxp=mtr

So the first axles are celica or sr5 and second are non lsd?
I'm trying to put lsd in a nonlsd 84 gts. Was hoping these would be what I needed?..

You should research further -- but as far as I can remember, only OE Toyota LSDs use axles that are 6 or 8mm shorter (?? exactly?). I'm pretty sure that TRD LSDs don't need shorter axles. Hopefully someone will chime in. Aftermarket LSDs definitely don't need shorter...

Your second diff pictured isn't an open diff like the caption says -- it's a TRD. Your axles will work if they're Kouki/Kouki.

The first LSD looks like an ancient Cusco (that are totally different from the newer ones -- and you can't get parts anymore)... I'd love to see inside that Cusco to see if has RS plates or the earlier ones you can't get.... Crack it open! It's a 1-way.

Test the preloads on them to see what shape they're in.... Both the bearing preload and the LSD preload... Squirt a bunch of diff oil into the LSD guts and work it in before you (or someone) measures the LSD preload... You can learn a lot before you stick it in a car or rebuild it... There is no sense using it if the preloads are way off. That Cusco one has a bit of a rusty ring gear... Hopefully not pitted.

There should be a number stamped on the side of the ring gear -- probably 4.3... ??

I did take a pic in the last one was a number stamped on gear. Thought it was 13 but is probably 43 like you said. Thanks for your help. I'll post another pic if I open them up.
