Hellical or mechanical ?, how to tell.. Options

[Culpable04]

I have trannies with LSD's I'm only keeping one, the issue is, one is a mechanical TRD LSD and the other is a hellical TRD LSD.

of course the guy who got them for me, didn't mark them down, so I don't know which one is which.

I want to keep the hellical as is maintance free, oppose to the mechanical that uses clutches.

if you have any idea of how to identify each without taking the engine apart, please share the acknowledge.

almost forgot,

these are E series trannies

as far as available information from toyota / TRD sites, there was no viscous LSD, the part numbers for the stock MR2 LSD correspond with the mechanical TRD LSD part numbers, and since the LSD was an option, I'm assuming they were all mechanical, but hopefully someone outthere has information that says otherwise.

my main issue is that if they are all mechanical, I'd need to rebuild one of them to use, and have a spare rebuild kit for when that goes.
viscous as the hellical just need an special oil and you never have to open them up.
