The seldom seen Johnex.....

Thanks for that info Richard. It's definately not what you've got pictured there.
When I asked what the DD designation was for at HOC, I was told "DeDion link". Is it possible DeDion designed more than one type of suspension ?
They had a independent suspended chassis there at that time that they called an EQ. It had inboard brakes and I believe it was probably a Jag.
I had never heard of DeDion before but it made sense to me that that would be were they got the DD from.
The pics in the galary don't show the whole setup very well. I'm going to have it up on a lift next week and will be able to get a better shot of it.
I have never seen a linkage setup like this before. The lower link attaches at the bottom of the housing under the diff and goes forward and outward on each side, forming a triangle and attaching to the frame rails ahead of the rear wheels. The upper links, which can be seen in the pictures, go straight back, attaching to the frame behind the wheels. It is fully adjustable for pinion angle and has anti squat/possitive lift characteristics under acceleration. It is very stable and puts power to the ground like a drag car.
Anyway... thanks for your response. I would be interested in any more info on where this suspension design came from. It seems to work pretty well.
