Actually there's a way to make it work but it requires fixed output flanges (anchored to the frame) and a "floating differential". The weight of the diff. shifting would disengage the outside wheel clutch/cone.

The more I think about it the more I'm convinced it's not designed right as is.

Not to be a PIA, just want the car to be the best. I have no doubt the Kirkhams do as well.

Actually I take that back, float the knuckles on the A-arm joints (for side to side movement) and switch to solid shafts. The driveshaft forces would effect a floating diff. I'd guess.
