Need info on 993 rear suspension conversion

Well, I did it!
It wasn't THAT difficult once the chassis was sitting and bolted on a frame, but I had a clean 993 on jacks on which I could make measurements.
First, I thought of making a steel or aluminum frame of my own that would respect the 993 anchor points for the arms. There were benefits: aluminum tubing would be lightweight and this would give the opportunity to increase camber etc.
However, this option requires to be really meticulous and relatively well equipped.
So I purchased the whole damn thing (like this: http://www.ebay.com/itm/Porsche-911-...02e4ed&vxp=mtr ) and it becomes more realistic for an amateur.
The one part that caused me trouble was the dampers, needing new housings in the 964 frame. I completely cut everything off (baffles around the engine bay) to give easier access and built them of 2mm thick chromoly sheets. Everything else was like playing with a kid's erector construction set requiring a lot of patience (cleaning, measuring, tacking, adjusting, welding... again and again).
I sold the car in 2012. I might be able to find pics.
To be honest, I would not do it again and would directly buy a 996. If someone's as crazy (or naive) as I've been, and wants to do it I have lots of parts left for the job. Maybe everything but hubs and spindles.

long bump. Curious to see if anyone else tackled this over the years?
