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?

We're considering going that route on a '76 resto-mod project that we kicked off recently. (Converting an entire 993 rear sub-frame / carrier into the older chassis!)
I would appreciate seeing progress pictures / steps described / completed pictures (with the engine still out), or any other input that might help us. If anybody would be kind enough to do that, please PM them to me, or email them to me directly - if you would rather not post here publicly... The car will be getting a 964 engine and a G50 or similar gearbox.
Thanks.
