open diff = no lsd, so there is no such thing.

I believe what the company is asking is...Does your car come factory with LSD? or Without? It's possible that there's an extra part or somethign that you'd need if you didn't have posi already.

it's so you order the appropriate part because on most makes the LSD rear and non-LSD rears have different output shafts for the rear axles.
