Aubrey's 62 409 goes 11.067 in C/S

It would not be hard at all to put the brackets on a 12 bolt correctly, honestly, the geometry is not all that complicated. The 12 bolt would be cheaper, faster, and more reliable. It just would not be as cool.

I seriously doubt there is a cost effective way to keep the original rear end in the car and have it be reliable. Much as I'd like to see it work, it would be pretty cool.
