Conversions & Hybrids - Picked Up The 6L80E Today

Ok, I picked up the 6L80E transmission today and hopefully this is the correct one that a 4L80 yoke will fit in. Anyone know for sure. This going with an L92 into my 1965 Buick Skylark. Here is the picture.

Do you have any way to weigh it? Looks like a monster.

I don't know but it was all two of us could do to lift it up and put it in the back of my Tahoe. It does have the flex plate and torque converter on so that made it that much heavier.
