identifying diff guts : LSD, HLSD or clutch

[Tenchuu]

OK here's the thing, I've searched to start, but I'm trying to tell what sort of diff is in this thing, and can't seem to bust loose the bolts with hand tools, any advice on how to? I know once I get it out how to tell if it's a HLSD, but the not sure on VLSD and clutch types (unless a bunch of clutch shit is obvious just hanging out inside) here's some pics

Not a diff I've seen. Not helical, not oem. So I'd guess it's a mechanical diff with ~80% confidence.

that's what i was thinking, i can hear a "clunk" sound whenever I try to turn the axles forward and then reverse. any more opinions would be nice. I am pretty sure what it isn't now.
is not:
nismo
KAAZ
cusco
tomi
HLSD
VLSD
at least not the same as pics I found of Silvia models of the diffs

well here's one that I took earlier

**********edit pic removed better ones put in new post***************

one guy said 2 way, but the jury is still out

Looks like a 2way with that even V(<0>). Take a shot at the other hole so we can see the plates and make out the manufacture.
